BODVDDD_VSEL
RW
A
0
Selects the voltage threshold for BOD on vddd. The
BOD does not reliably monitor the supply during the
transition.
0: vddd<2.7V
1: vddd<3.0V
3
BODVDDD_ENABLE
RW
A
1
Enable for BOD on vddd. This cannot be disabled
during normal operation.
4
BODVDDA_VSEL
RW
A
0
Selects the voltage threshold for BOD on vdda. Ensure
BODVDDA_ENABLE==0 before changing this setting
to prevent false triggers.
0: vdda<2.7V
1: vdda<3.0V
6:7
BODVDDA_ACTION
RW
A
0
Action taken when the BOD on vdda triggers.
NOTHING
0
No action
FAULT
1
Generate a fault
RESET
2
Reset the chip
8
BODVDDA_ENABLE
RW
A
0
Enable for BOD on vdda. BODVDDA_ACTION will be
triggered when the BOD is disabled. If no action is
desired when disabling, firmware must first write
BODVDDA_ACTION=NOTHING in a separate write
cycle.
11
BODVCCD_ENABLE
RW
A
1
Enable for BOD on vccd. This cannot be disabled
during normal operation.
