PMM_Status_t PMM_Sleep

(

PMM_SleepReq_t *

req

)

This function puts the system to sleep if possible.

Parameters

[in]

*req

- pointer to PMM_SleepReq_t request structure

Returns

value of type PMM_Status_t PMM_SLEEP_REQ_DENIED – when sleep is not possible at the instance PMM_SLEEP_REQ_PROCESSED – when sleep is possible and have already done
