sahilmgandhi 18:6a4db94011d3 113 *
sahilmgandhi 18:6a4db94011d3 114 * The System driver provides a collection of interfaces between the user
sahilmgandhi 18:6a4db94011d3 115 * application logic, and the core device functionality (such as clocks, reset
sahilmgandhi 18:6a4db94011d3 116 * cause determination, etc.) that is required for all applications. It contains
sahilmgandhi 18:6a4db94011d3 117 * a number of sub-modules that control one specific aspect of the device:
sahilmgandhi 18:6a4db94011d3 118 *
sahilmgandhi 18:6a4db94011d3 119 * - System Core (this module)

sahilmgandhi 18:6a4db94011d3 126 * \subsection asfdoc_sam0_system_module_overview_vreg_l21 Voltage Regulator
sahilmgandhi 18:6a4db94011d3 127 * The SAM device controls the voltage regulators for the core (VDDCORE) and
sahilmgandhi 18:6a4db94011d3 128 * backup (VDDBU) domains. It sets the voltage regulators according to the sleep
sahilmgandhi 18:6a4db94011d3 129 * modes, the performance level, or the user configuration.
sahilmgandhi 18:6a4db94011d3 130 *
sahilmgandhi 18:6a4db94011d3 131 * In active mode, the voltage regulator can be chosen on the fly between a LDO
sahilmgandhi 18:6a4db94011d3 132 * or a Buck converter. In standby mode, the low power voltage regulator is used
sahilmgandhi 18:6a4db94011d3 133 * to supply VDDCORE.
sahilmgandhi 18:6a4db94011d3 134 *

sahilmgandhi 18:6a4db94011d3 136 * The SAM device supports connection of a battery backup to the VBAT power pin.
sahilmgandhi 18:6a4db94011d3 137 * It includes functionality that enables automatic power switching between main
sahilmgandhi 18:6a4db94011d3 138 * power and battery backup power. This will ensure power to the backup domain,
sahilmgandhi 18:6a4db94011d3 139 * when the main battery or power source is unavailable.

sahilmgandhi 18:6a4db94011d3 145 * the voltage regulators according to the sleep modes.
sahilmgandhi 18:6a4db94011d3 146 *
sahilmgandhi 18:6a4db94011d3 147 * There are a selectable reference voltage and voltage dependent on the temperature
sahilmgandhi 18:6a4db94011d3 148 * which can be used by analog modules like the ADC.

sahilmgandhi 18:6a4db94011d3 152 * The various analog modules within the SAM devices (such as AC, ADC, and
sahilmgandhi 18:6a4db94011d3 153 * DAC) require a voltage reference to be configured to act as a reference point
sahilmgandhi 18:6a4db94011d3 154 * for comparisons and conversions.
sahilmgandhi 18:6a4db94011d3 155 *
sahilmgandhi 18:6a4db94011d3 156 * The SAM devices contain multiple references, including an internal
sahilmgandhi 18:6a4db94011d3 157 * temperature sensor and a fixed band-gap voltage source. When enabled, the
sahilmgandhi 18:6a4db94011d3 158 * associated voltage reference can be selected within the desired peripheral
sahilmgandhi 18:6a4db94011d3 159 * where applicable.

sahilmgandhi 18:6a4db94011d3 162 * In some applications there may be a need to execute a different program
sahilmgandhi 18:6a4db94011d3 163 * flow based on how the device was reset. For example, if the cause of reset
sahilmgandhi 18:6a4db94011d3 164 * was the Watchdog timer (WDT), this might indicate an error in the application,
sahilmgandhi 18:6a4db94011d3 165 * and a form of error handling or error logging might be needed.
sahilmgandhi 18:6a4db94011d3 166 *
sahilmgandhi 18:6a4db94011d3 167 * For this reason, an API is provided to retrieve the cause of the last system
sahilmgandhi 18:6a4db94011d3 168 * reset, so that appropriate action can be taken.
sahilmgandhi 18:6a4db94011d3 169 *
sahilmgandhi 18:6a4db94011d3 170 * \if DEVICE_SAML21_SYSTEM_SUPPORT
sahilmgandhi 18:6a4db94011d3 171 * There are three groups of reset sources:
sahilmgandhi 18:6a4db94011d3 172 * - Power supply reset: Resets caused by an electrical issue. It covers POR and BOD reset.
sahilmgandhi 18:6a4db94011d3 173 * - User reset: Resets caused by the application. It covers external reset,
sahilmgandhi 18:6a4db94011d3 174 * system reset, and watchdog reset.
sahilmgandhi 18:6a4db94011d3 175 * - Backup reset: Resets caused by a backup mode exit condition.
sahilmgandhi 18:6a4db94011d3 176 *
sahilmgandhi 18:6a4db94011d3 177 * \subsection asfdoc_sam0_system_module_overview_performance_level Performance Level
sahilmgandhi 18:6a4db94011d3 178 * Performance level allows the user to adjust the regulator output voltage to reduce
sahilmgandhi 18:6a4db94011d3 179 * power consumption. The user can on the fly select the most suitable performance
sahilmgandhi 18:6a4db94011d3 180 * level, depending on the application demands.
sahilmgandhi 18:6a4db94011d3 181 *
sahilmgandhi 18:6a4db94011d3 182 * The SAM device can operate at two different performance levels (PL0 and PL2).
sahilmgandhi 18:6a4db94011d3 183 * When operating at PL0, the voltage applied on the full logic area is reduced
sahilmgandhi 18:6a4db94011d3 184 * by voltage scaling. This voltage scaling technique allows to reduce the active
sahilmgandhi 18:6a4db94011d3 185 * power consumption while decreasing the maximum frequency of the device. When
sahilmgandhi 18:6a4db94011d3 186 * operating at PL2, the voltage regulator supplies the highest voltage, allowing
sahilmgandhi 18:6a4db94011d3 187 * the device to run at higher clock speeds.
sahilmgandhi 18:6a4db94011d3 188 *
sahilmgandhi 18:6a4db94011d3 189 * Performance level transition is possible only when the device is in active
sahilmgandhi 18:6a4db94011d3 190 * mode. After a reset, the device starts at the lowest performance level
sahilmgandhi 18:6a4db94011d3 191 * (lowest power consumption and lowest max. frequency). The application can then
sahilmgandhi 18:6a4db94011d3 192 * switch to another performance level at any time without any stop in the code
sahilmgandhi 18:6a4db94011d3 193 * execution. As shown in \ref asfdoc_sam0_system_performance_level_transition_figure.
sahilmgandhi 18:6a4db94011d3 194 *
sahilmgandhi 18:6a4db94011d3 195 * \note When scaling down the performance level, the bus frequency should first be
sahilmgandhi 18:6a4db94011d3 196 * scaled down in order to not exceed the maximum frequency allowed for the
sahilmgandhi 18:6a4db94011d3 197 * low performance level.
sahilmgandhi 18:6a4db94011d3 198 * When scaling up the performance level (e.g. from PL0 to PL2), check the performance
sahilmgandhi 18:6a4db94011d3 199 * level status before increasing the bus frequency. It can be increased only
sahilmgandhi 18:6a4db94011d3 200 * when the performance level transition is completed.

sahilmgandhi 18:6a4db94011d3 205 * \subsection asfdoc_sam0_system_module_overview_power_domain Power Domain Gating
sahilmgandhi 18:6a4db94011d3 206 * Power domain gating allows power saving by reducing the voltage in logic
sahilmgandhi 18:6a4db94011d3 207 * areas in the device to a low-power supply. The feature is available in
sahilmgandhi 18:6a4db94011d3 208 * Standby sleep mode and will reduce the voltage in domains where all peripherals
sahilmgandhi 18:6a4db94011d3 209 * are idle. Internal logic will maintain its content, meaning the corresponding
sahilmgandhi 18:6a4db94011d3 210 * peripherals will not need to be reconfigured when normal operating voltage
sahilmgandhi 18:6a4db94011d3 211 * is returned. Most power domains can be in the following three states:
sahilmgandhi 18:6a4db94011d3 212 *
sahilmgandhi 18:6a4db94011d3 213 * - Active state: The power domain is powered on.
sahilmgandhi 18:6a4db94011d3 214 * - Retention state: The main voltage supply for the power domain is switched off,
sahilmgandhi 18:6a4db94011d3 215 * while maintaining a secondary low-power supply for the sequential cells. The
sahilmgandhi 18:6a4db94011d3 216 * logic context is restored when waking up.
sahilmgandhi 18:6a4db94011d3 217 * - Off state: The power domain is entirely powered off. The logic context is lost.
sahilmgandhi 18:6a4db94011d3 218 *
sahilmgandhi 18:6a4db94011d3 219 * The SAM L21 device contains three power domains which can be controlled using
sahilmgandhi 18:6a4db94011d3 220 * power domain gating, namely PD0, PD1, and PD2. These power domains can be
sahilmgandhi 18:6a4db94011d3 221 * configured to the following cases:
sahilmgandhi 18:6a4db94011d3 222 * - Default with no sleepwalking peripherals: A power domain is automatically set
sahilmgandhi 18:6a4db94011d3 223 * to retention state in standby sleep mode if no activity require it. The application
sahilmgandhi 18:6a4db94011d3 224 * can force all power domains to remain in active state during standby sleep mode

sahilmgandhi 18:6a4db94011d3 230 * power domain (PDn) in active can wake up a superior power domain (>PDn) in order
sahilmgandhi 18:6a4db94011d3 231 * to perform a sleepwalking task. The superior power domain is then automatically
sahilmgandhi 18:6a4db94011d3 232 * set to active state. At the end of the sleepwalking task, the device can either
sahilmgandhi 18:6a4db94011d3 233 * be woken up or the superior power domain can return to retention state.
