10.3.2.13 Low Voltage Control Register (CPMULVCTL)
The CPMULVCTL register allows the configuration of the low-voltage detect features.
Read: Anytime
Write: LVIE and LVIF are write anytime, LVDS is read only

Low-Voltage Detect Status Bit — This read-only status bit reflects the voltage level on VDDA. Writes have no
effect.
0 Input voltage VDDA is above level V
1 Input voltage VDDA is below level V
Low-Voltage Interrupt Enable Bit
0 Interrupt request is disabled.
1 Interrupt will be requested whenever LVIF is set.
Low-Voltage Interrupt Flag — LVIF is set to 1 when LVDS status bit changes. This flag can only be cleared by
writing a 1. Writing a 0 has no effect. If enabled (LVIE = 1), LVIF causes an interrupt request.
0 No change in LVDS bit.
1 LVDS bit has changed.
