##### Peripheral Extended control functions #####

|
===============================================================================
|
|
*** PVD configuration (present on all other devices than STM32F3x8 devices) ***
|
|
=========================
|
|
[..]
|
|
(+) The PVD is used to monitor the VDD power supply by comparing it to a
|
|
threshold selected by the PVD Level (PLS[2:0] bits in the PWR_CR).
|
|
(+) A PVDO flag is available to indicate if VDD/VDDA is higher or lower
|
|
than the PVD threshold. This event is internally connected to the EXTI
|
|
line16 and can generate an interrupt if enabled. This is done through
|
|
__HAL_PWR_PVD_EXTI_ENABLE_IT() macro
|
|
(+) The PVD is stopped in Standby mode.
|
|
-@- PVD is not available on STM32F3x8 Product Line
|
|
|
|
|
|
*** Voltage regulator ***
|
|
=========================
|
|
[..]
|
|
(+) The voltage regulator is always enabled after Reset. It works in three different
|
|
modes.
|
|
In Run mode, the regulator supplies full power to the 1.8V domain (core, memories
|
|
and digital peripherals).
|
|
In Stop mode, the regulator supplies low power to the 1.8V domain, preserving
|
|
contents of registers and SRAM.
|
|
In Stop mode, the regulator is powered off. The contents of the registers and SRAM
|
|
are lost except for the Standby circuitry and the Backup Domain.
|
|
Note: in the STM32F3x8xx devices, the voltage regulator is bypassed and the
|
|
microcontroller must be powered from a nominal VDD = 1.8V +/-8U% voltage.
|
|
|
|
|
|
(+) A PVDO flag is available to indicate if VDD/VDDA is higher or lower
|
|
than the PVD threshold. This event is internally connected to the EXTI
|
|
line16 and can generate an interrupt if enabled. This is done through
|
|
__HAL_PWR_PVD_EXTI_ENABLE_IT() macro
|
|
(+) The PVD is stopped in Standby mode.
|
|
|
|
|
|
*** SDADC power configuration ***
|
|
================================
|
|
[..]
|
|
(+) On STM32F373xC/STM32F378xx devices, there are up to
|
|
3 SDADC instances that can be enabled/disabled.
