void HAL_PWR_EnterSTOPMode(uint32_t Regulator, uint8_t STOPEntry);

Implemented in stm32f4xx_hal_pwr.c:445

Arguments

Argument

Declared as

Description

Regulator

uint32_t

Specifies the regulator state in Stop mode. This parameter can be one of the following values: @arg PWR_MAINREGULATOR_ON: Stop mode with regulator ON @arg PWR_LOWPOWERREGULATOR_ON: Stop mode with low power regulator ON

STOPEntry

uint8_t

Specifies if Stop mode in entered with WFI or WFE instruction. This parameter can be one of the following values: @arg PWR_STOPENTRY_WFI : Enter Stop mode with WFI instruction @arg PWR_STOPENTRY_WFE : Enter Stop mode with WFE instruction and clear of pending events before. @arg PWR_STOPENTRY_WFE_NO_EVT_CLEAR : Enter STOP mode with WFE instruction and no clear of pending event before.

Return value

None

Notes

In Stop mode, all I/O pins keep the same state as in Run mode. When exiting Stop mode by issuing an interrupt or a wake-up event, the HSI RC oscillator is selected as system clock. When the voltage regulator operates in low power mode, an additional startup delay is incurred when waking up from Stop mode. By keeping the internal regulator ON during Stop mode, the consumption is higher although the startup time is reduced.
