void AUXSYSIFOpModeChange

(

uint32_t

targetOpMode

)

Changes the AUX operational mode to the requested target mode.

This function controls the change of the AUX operational mode. The function controls the change of the current operational mode to the operational mode target by adhering to rules specified by HW.

Parameters

targetOpMode

AUX operational mode: AUX_SYSIF_OPMODE_TARGET_PDLP (Powerdown operational mode with wakeup to lowpower mode) AUX_SYSIF_OPMODE_TARGET_PDA (Powerdown operational mode with wakeup to active mode) AUX_SYSIF_OPMODE_TARGET_LP (Lowpower operational mode) AUX_SYSIF_OPMODE_TARGET_A (Active operational mode)

Returns

None
