PMC Memory Map/Register Definition
Address: PMC_LVDSC1 is 4007_D000h base + 0h offset = 4007_D000h
14.4.2 Low Voltage Detect Status and Control 2 Register
This register contains status and control bits to support the low voltage warning function.
While the device is in the very low power or low leakage modes, the LVD system is
disabled regardless of LVDSC2 settings.

Low-Voltage Detect Flag
This read-only status bit indicates a low-voltage detect event.
0

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.
Low-Voltage Detect Interrupt Enable
Enables hardware interrupt requests for LVDF.

1
Low-Voltage Detect Reset Enable
This write-once bit enables LVDF events to generate a hardware reset. Additional writes are ignored.
