31.3.1.5 Functional Event Alternate Request Register (RGM_FEAR)
This register defines an alternate request to be generated when a reset on a functional event has been
disabled. The alternate request can be either a Safe mode request to MC_ME or an interrupt request to the
system. It can be accessed in read/write in either supervisor mode or test mode. It can be accessed in read
only in user mode.

Field Description
D_LVD27 Disable 2.7V low-voltage detected
0 A 2.7V low-voltage detected event triggers a reset sequence
1 A 2.7V low-voltage detected event generates either a Safe mode or an interrupt request depending on the
value of RGM_DEAR.AR_LVD27
D_SWT Disable software watchdog timer
0 A software watchdog timer event triggers a reset sequence
1 A software watchdog timer event generates either a Safe mode or an interrupt request depending on the value
of RGM_DEAR

Disable 1.2V low-voltage detected (power domain #1)
0 A 1.2V low-voltage detected (power domain #1) event triggers a reset sequence
1 A 1.2V low-voltage detected (power domain #1) event generates either a Safe mode or an interrupt request
depending on the value of RGM_DEAR.AR_LVD12_PD1
D_LVD12_P
D0
Disable 1.2V low-voltage detected (power domain #0)
0 A 1.2V low-voltage detected (power domain #0) event triggers a reset sequence
