Figure 32-5. Destructive Event Reset Disable Register (RGM_DERD)
This register provides dedicated bits to disable particular destructive reset sources. When a destructive
reset source is disabled, the associated destructive event will trigger either a safe mode request or an
interrupt request (see Section 32.3.1.6, Destructive Event Alternate Request Register (RGM_DEAR)). It
can be accessed in read/write in either supervisor mode or test mode. It can be accessed in read only in user
mode. Each byte can be written only once after power-on reset.

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.AR_SWT
D_LVD12_P
D1
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
1 A 1.2V low-voltage detected (power domain #0) event generates either a SAFE mode or an interrupt request
depending on the value of RGM_DEAR.AR_LVD12_PD0
