9.3.1.7 Functional Event Short Sequence Register (RGM_FESS)
This register defines which reset sequence will be done when a functional reset sequence is triggered.The
functional reset sequence can either start from PHASE1 or from PHASE3, skipping PHASE1 and
PHASE2.
NOTE
This could be useful for fast reset sequence, for example to skip flash reset.
It can be accessed in read/write in either supervisor mode or test mode. It can be accessed in read in user
mode.
AR_LVD12_
PD1
Alternate Request for 1.2 V low-voltage detected (power domain #1)
0 Generate a SAFE mode request on a 1.2 V low-voltage detected (power domain #1) event if the
reset is disabled
1 Generate an interrupt request on a 1.2 V low-voltage detected (power domain #1) event if the reset
is disabled
AR_LVD12_
PD0
Alternate Request for 1.2 V low-voltage detected (power domain #0)
0 Generate a SAFE mode request on a 1.2 V low-voltage detected (power domain #0) event if the
reset is disabled
1 Generate an interrupt request on a 1.2 V low-voltage detected (power domain #0) event if the reset
is disabled

Field Description
SS_EXR Short Sequence for External Reset
0 The reset sequence triggered by an external reset event will start from PHASE1
1 The reset sequence triggered by an external reset event will start from PHASE3, skipping
PHASE1 and PHASE2
SS_FLASH Short Sequence for code or data flash fatal error
0 The reset sequence triggered by a code or data flash fatal error event will start from PHASE1
1 The reset sequence triggered by a code or data flash fatal error event will start from PHASE3,
skipping PHASE1 and PHASE2
