Return to the Summary Table.

Operational Mode Request
AUX can operate in three operational modes. Each mode is associated with:
- a SCE clock source or rate, given by AON_PMCTL:AUXSCECLK. This rate is termed SCE_RATE.
- a system power supply state request. AUX can request powerdown (uLDO) or active (GLDO or DCDC) system power supply state.
- a specific system response to an active AUX wakeup flag. The response is dependent on what operational mode is requested.
uLDO power supply state offers limited current supply. AUX_SCE cannot use certain peripherals and functions such as AUX_DDI0_OSC, AUX_TDC and AUX_ANAIF ADC interface in this power supply state.
Follow these rules:
- It is not allowed to change a request until it has been acknowledged through OPMODEACK.
- A change in mode request must happen stepwise along this sequence, the direction is irrelevant:
PDA - A - LP - PDLP.
Failure to follow these rules might result in unexpected behavior and must be avoided.

AUX operational mode request.

0h = Active operational mode, characterized by:
- Active system power supply state (GLDO or DCDC) request.
- AON_PMCTL:AUXSCECLK.SRC sets the SCE clock frequency (SCE_RATE).
- An active wakeup flag does not change operational mode.

1h = Lowpower operational mode, characterized by:
- Powerdown system power supply state (uLDO) request.
- SCE clock frequency (SCE_RATE) equals SCLK_MF.
- An active wakeup flag does not change operational mode.

2h = Powerdown operational mode with wakeup to active mode, characterized by:
- Powerdown system power supply state (uLDO) request.
- AON_PMCTL:AUXSCECLK.PD_SRC sets the SCE clock frequency (SCE_RATE).
- An active wakeup flag overrides the operational mode externally to active (A) as long as the flag is set.

3h = Powerdown operational mode with wakeup to lowpower mode, characterized by:
- Powerdown system power supply state (uLDO) request.
- AON_PMCTL:AUXSCECLK.PD_SRC sets the SCE clock frequency (SCE_RATE).
- An active wakeup flag overrides the operational mode externally to lowpower (LP) as long as the flag is set.

Operational Mode Acknowledgement

Programmable Wakeup 0 Configuration
Configure this register to enable a customized AUX wakeup flag. The wakeup flag will be captured by AON_PMCTL which responds according to the current operational mode. You can select WUFLAGS.PROG_WU0 to trigger execution of a programmable AUX_SCE vector by configuration of VECCFGn. You need to follow the procedure described in WUFLAGSCLR to clear this flag. You need to follow the procedure described in WUGATE to configure it.

Wakeup Flags Clear
This register clears AUX wakeup flags WUFLAGS.
To clear programmable wakeup flags you must disable the AUX wakeup output first. After the programmable wakeup flags are cleared you must re-enable the AUX wakeup output. Write WUGATE to disable or enable the AUX wakeup output. This procedure is not required when you want to clear a software-triggered wakeup.

Wakeup Gate
You must disable the AUX wakeup output:
- Before you clear a programmable wakeup flag.
- Before you change the value of [PROGWUnCFG.EN] or [PROGWUnCFG.WU_SRC].
The AUX wakeup output must be re-enabled after clear operation or programmable wakeup configuration.

Clock Shift Detection
A transition in the MCU domain state causes a non-accumulative change to the SCE clock period when the AUX clock rate is derived from SCLK_MF or SCLK_LF:
- A single SCE clock cycle is 6 thru 8 SCLK_HF cycles longer when MCU domain enters active state.
- A single SCE clock cycle is 6 thru 8 SCLK_HF cycles shorter when MCU domain exits active state.

AUX_SCE detects if such events occurred to the SCE clock during the time period between a clear of STAT and a read of STAT.
