VDDSTAT
VDD/DC+ Supply Monitor Enable.
This bit turns the VDD/DC+ supply monitor circuit on/off. The VDD/DC+ Supply
Monitor cannot generate system resets until it is also selected as a reset source in
register RSTSRC (SFR Definition 18.2).
0: VDD/DC+ Supply Monitor Disabled.
1: VDD/DC+ Supply Monitor Enabled.
VDD/DC+ Supply Status.
This bit indicates the current power supply status.
0: VDD/DC+ is at or below the V
1: VDD/DC+ is above the V
VDD/DC+ Supply Status (Early Warning).
This bit indicates the current VDD/DC+ power supply status.
0: VDD/DC+ is at or below the VDD
1: VDD/DC+ is above the VDD
VBAT Supply Status (Early Warning).
This bit indicates the current VBAT power supply status. This bit is only present on
‘F912 and ‘F902 devices.
0: VBAT is at or below the VBAT
1: VBAT is above the VBAT
VDD/DC+ Early Warning Interrupt Enable.
Enables the VDD/DC+ Early Warning Interrupt. This bit only has an effect on ‘F912
and ‘F902 devices. All other devices behave as if this bit is set to 1.
0: VDD/DC+ Early Warning Interrupt is disabled.
1: VDD/DC+ Early Warning Interrupt is enabled.
VBAT Early Warning Interrupt Enable.
Enables the VBAT Early Warning Interrupt. This bit only has an effect on ‘F912 and
‘F902 devices. All other devices behave as if this bit is set to 0.
0: VBAT Early Warning Interrupt is disabled.
1: VBAT Early Warning Interrupt is enabled.
Unused.
