 *
 * This driver for Atmel&reg; | SMART SAM devices provides an interface for the
 * configuration and management of the device's physical I/O Pins, to alter the
 * direction and input/drive characteristics as well as to configure the pin
 * peripheral multiplexer selection.
 *
 * The following peripherals are used by this module:
 *  - PORT (Port I/O Management)
 *
 * The following devices can use this module:
 *  - Atmel | SMART SAM D20/D21
 *  - Atmel | SMART SAM R21
 *  - Atmel | SMART SAM D10/D11
 *  - Atmel | SMART SAM L21
 *  - Atmel | SMART SAM DAx
 *  - Atmel | SMART SAM C20/C21
 *
 * Physically, the modules are interconnected within the device as shown in the
 * following diagram:
 *
 * The outline of this documentation is as follows:

 *  - \ref asfdoc_sam0_system_pinmux_module_overview
 *  - \ref asfdoc_sam0_system_pinmux_special_considerations

 *
 * \section asfdoc_sam0_system_pinmux_prerequisites Prerequisites
 *
 * There are no prerequisites for this module.
 *
 *
 * \section asfdoc_sam0_system_pinmux_module_overview Module Overview
 *
 * The SAM devices contain a number of General Purpose I/O pins, used to
 * interface the user application logic and internal hardware peripherals to
 * an external system. The Pin Multiplexer (PINMUX) driver provides a method
 * of configuring the individual pin peripheral multiplexers to select
 * alternate pin functions.
 *
 * \subsection asfdoc_sam0_system_pinmux_features Driver Feature Macro Definition
 * <table>
 *  <tr>
 *    <th>Driver Feature Macro</th>
 *    <th>Supported devices</th>
 *  </tr>
 *  <tr>
 *    <td>FEATURE_SYSTEM_PINMUX_DRIVE_STRENGTH</td>
 *    <td>SAML21, SAMC20/C21</td>
 *  </tr>
 * </table>
 * \note The specific features are only available in the driver when the
 * selected device supports those features.
 *
 * \subsection asfdoc_sam0_system_pinmux_physical_logical_pins Physical and Logical GPIO Pins
 * SAM devices use two naming conventions for the I/O pins in the device; one
 * physical and one logical. Each physical pin on a device package is assigned
 * both a physical port and pin identifier (e.g. "PORTA.0") as well as a
 * monotonically incrementing logical GPIO number (e.g. "GPIO0"). While the
 * former is used to map physical pins to their physical internal device module
 * counterparts, for simplicity the design of this driver uses the logical GPIO
 * numbers instead.
 *
 * \subsection asfdoc_sam0_system_pinmux_peripheral_muxing Peripheral Multiplexing
 * SAM devices contain a peripheral MUX, which is individually controllable
 * for each I/O pin of the device. The peripheral MUX allows you to select the
 * function of a physical package pin - whether it will be controlled as a user
 * controllable GPIO pin, or whether it will be connected internally to one of
 * several peripheral modules (such as an I<SUP>2</SUP>C module). When a pin is
 * configured in GPIO mode, other peripherals connected to the same pin will be
 * disabled.
 *
 * \subsection asfdoc_sam0_system_pinmux_pad_characteristics Special Pad Characteristics
 * There are several special modes that can be selected on one or more I/O pins
 * of the device, which alter the input and output characteristics of the pad.
 *
 * \subsubsection asfdoc_sam0_system_pinmux_drive_strength Drive Strength
 * The Drive Strength configures the strength of the output driver on the
 * pad. Normally, there is a fixed current limit that each I/O pin can safely
 * drive, however some I/O pads offer a higher drive mode which increases this
 * limit for that I/O pin at the expense of an increased power consumption.
 *
 * \subsubsection asfdoc_sam0_system_pinmux_slew_rate Slew Rate
 * The Slew Rate configures the slew rate of the output driver, limiting the
 * rate at which the pad output voltage can change with time.
 *
 * \subsubsection asfdoc_sam0_system_pinmux_input_sample_mode Input Sample Mode
 * The Input Sample Mode configures the input sampler buffer of the pad. By
 * default, the input buffer is only sampled "on-demand", i.e. when the user
 * application attempts to read from the input buffer. This mode is the most
 * power efficient, but increases the latency of the input sample by two clock
 * cycles of the port clock. To reduce latency, the input sampler can instead
 * be configured to always sample the input buffer on each port clock cycle, at
 * the expense of an increased power consumption.
 *
 * \subsection asfdoc_sam0_system_pinmux_module_overview_physical Physical Connection
 *
 * \ref asfdoc_sam0_system_pinmux_intconnections "The diagram below" shows
 * how this module is interconnected within the device:

 *   pad    -> pinmux;
 *   pinmux -> peripherals;
 * }
 * \enddot
 *
 * \section asfdoc_sam0_system_pinmux_special_considerations Special Considerations
 *
 * The SAM port pin input sampling mode is set in groups of four physical
 * pins; setting the sampling mode of any pin in a sub-group of eight I/O pins
 * will configure the sampling mode of the entire sub-group.
 *
 * High Drive Strength output driver mode is not available on all device pins -
 * refer to your device specific datasheet.
