17.8.4.5 AUXCTL Register (Offset = 10h) [reset = X]

AUXCTL is shown in Figure 17-40 and described in Table 17-61.

Table 17-61. AUXCTL Register Field Descriptions

Bit Field Type Reset Description

31 RESET_REQ R/W X

Reset request for AUX. Writing 1 to this register will assert reset to

AUX. The reset will be held until the bit is cleared again. 0: AUX

reset pin will be deasserted 1: AUX reset pin will be asserted

30-3 RESERVED R X

Software should not rely on the value of a reserved. Writing any

other value than the reset value may result in undefined behavior.

2 SCE_RUN_EN R/W X

Enables (1) or disables (0) AUX_SCE execution. AUX_SCE

execution will begin when AUX Domain is powered and either this or

AUX_SCE:CTL.CLK_EN is set. Setting this bit will assure that

AUX_SCE execution starts as soon as AUX power domain is woken

up. ( AUX_SCE:CTL.CLK_EN will be reset to 0 if AUX power domain

has been off) 0: AUX_SCE execution will be disabled if

AUX_SCE:CTL.CLK_EN is 0 1: AUX_SCE execution is enabled.

1 SWEV R/W X

Writing 1 sets the software event to the AUX domain, which can be

read through AUX_WUC:WUEVFLAGS.AON_SW. This event is

normally cleared by AUX_SCE through the

AUX_WUC:WUEVCLR.AON_SW. It can also be cleared by writing 0

to this register. Reading 0 means that there is no outstanding

software event for AUX. Note that it can take up to 1,5 SCLK_LF

clock cycles to clear the event from AUX.

0 AUX_FORCE_ON R/W X

Forces the AUX domain into active mode, overriding the requests

from AUX_WUC:PWROFFREQ, AUX_WUC:PWRDWNREQ and

AUX_WUC:MCUBUSCTL. Note that an ongoing

AUX_WUC:PWROFFREQ will complete before this bit will set the

AUX domain into active mode. MCU must set this bit in order to

access the AUX peripherals. The AUX domain status can be read

from PWRSTAT.AUX_PD_ON 0: AUX is allowed to Power Off,

Power Down or Disconnect. 1: AUX Power OFF, Power Down or

Disconnect requests will be overruled
