mbed_official 237:f3da66175598 96 *** PVD configuration (present on all other devices than STM32F3x8 devices) ***
mbed_official 237:f3da66175598 97 =========================
mbed_official 237:f3da66175598 98 (+) The PVD is used to monitor the VDD power supply by comparing it to a
mbed_official 237:f3da66175598 99 threshold selected by the PVD Level (PLS[2:0] bits in the PWR_CR).
mbed_official 237:f3da66175598 100 (+) A PVDO flag is available to indicate if VDD/VDDA is higher or lower
mbed_official 237:f3da66175598 101 than the PVD threshold. This event is internally connected to the EXTI
mbed_official 237:f3da66175598 102 line16 and can generate an interrupt if enabled. This is done through
mbed_official 237:f3da66175598 103 __HAL_PVD_EXTI_ENABLE_IT() macro
mbed_official 237:f3da66175598 104 (+) The PVD is stopped in Standby mode.
mbed_official 237:f3da66175598 105 (+) Note: PVD is not available on STM32F3x8 Product Line

mbed_official 237:f3da66175598 108 *** Voltage regulator ***
mbed_official 237:f3da66175598 109 =========================
mbed_official 237:f3da66175598 110 (+) The voltage regulator is always enabled after Reset. It works in three different
mbed_official 237:f3da66175598 111 modes:
mbed_official 237:f3da66175598 112 In Run mode, the regulator supplies full power to the 1.8V domain (core, memories
mbed_official 237:f3da66175598 113 and digital peripherals).
mbed_official 237:f3da66175598 114 In Stop mode, the regulator supplies low power to the 1.8V domain, preserving
mbed_official 237:f3da66175598 115 contents of registers and SRAM.
mbed_official 237:f3da66175598 116 In Stop mode, the regulator is powered off. The contents of the registers and SRAM
mbed_official 237:f3da66175598 117 are lost except for the Standby circuitry and the Backup Domain.
mbed_official 237:f3da66175598 118 Note: In the STM32F3x8xx devices, the voltage regulator is bypassed and the
mbed_official 237:f3da66175598 119 microcontroller must be powered from a nominal VDD = 1.8V +/-8% voltage.

mbed_official 237:f3da66175598 121
mbed_official 237:f3da66175598 122 (+) A PVDO flag is available to indicate if VDD/VDDA is higher or lower
mbed_official 237:f3da66175598 123 than the PVD threshold. This event is internally connected to the EXTI
mbed_official 237:f3da66175598 124 line16 and can generate an interrupt if enabled. This is done through
mbed_official 237:f3da66175598 125 __HAL_PVD_EXTI_ENABLE_IT() macro
mbed_official 237:f3da66175598 126 (+) The PVD is stopped in Standby mode.

mbed_official 237:f3da66175598 128
mbed_official 237:f3da66175598 129 *** SDADC power configuration ***
mbed_official 237:f3da66175598 130 ================================
mbed_official 237:f3da66175598 131 (+) On STM32F373xC/STM32F378xx devices, there are up to
