void EnableDeepSleepIRQ ( IRQn_Type interrupt )

Enable the interrupt for wake-up from deep sleep mode. Some interrupts are typically used in sleep mode only and will not occur during deep-sleep mode because relevant clocks are stopped. However, it is possible to enable those clocks (significantly increasing power consumption in the reduced power mode), making these wake-ups possible.

Note: This function also enables the interrupt in the NVIC (EnableIRQ() is called internally).

Parameters

interrupt The IRQ number.

Returns: none

void DisableDeepSleepIRQ ( IRQn_Type interrupt )

Disable the interrupt for wake-up from deep sleep mode. Some interrupts are typically used in sleep mode only and will not occur during deep-sleep mode because relevant clocks are stopped. However, it is possible to enable those clocks (significantly increasing power consumption in the reduced power mode), making these wake-ups possible.

Note: This function also disables the interrupt in the NVIC (DisableIRQ() is called internally).

Parameters

interrupt The IRQ number.

Returns: none

uint32_t POWER_GetLibVersion ( void )

Parameters

none

Returns: version number of the power library
