Low-Voltage Detect Flag — Provided LVDE = 1, this read-only status bit indicates a low-voltage detect error.
Low-Voltage Detect Acknowledge — This write-only bit is used to acknowledge low voltage detection errors
(write 1 to clear LVDF). Reads always return logic 0.
Low-Voltage Detect Interrupt Enable — This read/write bit enables hardware interrupt requests for LVDF.
0 Hardware interrupt disabled (use polling).
1 Request a hardware interrupt when LVDF = 1.
SAFE System from interrupts — This read/write bit enables hardware to block interrupts and resets from
waking the MCU from stop mode while the supply voltage V

0 Enable pending interrupts and resets
1 Interrupts and resets are blocked while supply voltage is below re-arm voltage
Low-Voltage Detect Reset Enable — This bit enables the LVD reset function. This bit can be written only once
after a reset and additional writes have no meaning or effect. It is set following a POR and is unaffected by any
other resets, including an LVD reset.
0 LVDF does not generate hardware resets.
1 Force an MCU reset when LVDF = 1.
