__HAL_RCC_SYSCFG_CLK_SLEEP_ENABLE

#define __HAL_RCC_SYSCFG_CLK_SLEEP_ENABLE

(

)

(RCC->APB2LPENR |= (RCC_APB2LPENR_SYSCFGLPEN))

Note

Peripheral clock gating in SLEEP mode can be used to further reduce power consumption.

After wakeup from SLEEP mode, the peripheral clock is enabled again.

By default, all peripheral clocks are enabled during SLEEP mode.

__HAL_RCC_WWDG_CLK_SLEEP_ENABLE

#define __HAL_RCC_WWDG_CLK_SLEEP_ENABLE

(RCC->APB1LPENR |= (RCC_APB1LPENR_WWDGLPEN))

Note

Peripheral clock gating in SLEEP mode can be used to further reduce power consumption.

After wakeup from SLEEP mode, the peripheral clock is enabled again.

By default, all peripheral clocks are enabled during SLEEP mode.
