This high-page register contains status and control bits to support the low voltage detect function, and to
enable the bandgap voltage reference for use by the ADC module. To configure the low voltage detect trip
voltage, see

Bit 1 is a reserved bit that must always be written to 0.
This bit can be written only one time after reset. Additional writes are ignored.
Values are shown in this column based on t
value.
The initial RTI timeout period will be up to one 1 kHz clock period less than the time specified.

Low-Voltage Detect Flag — Provided LVDE = 1, this read-only status bit indicates a low-voltage detect event.
Low-Voltage Detect Acknowledge — This write-only bit is used to acknowledge low voltage detection errors
(write 1 to clear LVDF). Reads always return 0.
