Hi !

 

Can  POWER_EnterPowerDown API be called in nonprivileged mode ?

 

in UM mentioned :

"

• CPU0 interrupt enable registers (NVIC->ISER) are modified by
POWER_EnterDeepSleep, POWER_EnterPowerDown, and
POWER_EnterDeepPowerDown power APIs. They are restored in case of CPU
retention (deep-sleep and in power-down) or if the low power mode is not entered (for
example, a pending interrupt).

"

and NVIC->ISER require privileged access.

Or API able to escalate privilege if need ?

 

Regards,

Eugene
