The IRVST bit is usable only when the HFINTOSC is running.
Not tested and below minimum operating conditions.
x = unknown, - = unimplemented read as ‘0’. Shaded cells are not used by the PLVD module.

Unimplemented: Read as ‘0’
IRVST: Internal Reference Voltage Stable Status Flag bit
1 = Indicates that the PLVD is stable and PLVD interrupt is reliable
0 = Indicates that the PLVD is not stable and PLVD interrupt must not be enabled
LVDEN: Low-Voltage Detect Module Enable bit
1 = Enables PLVD Module, powers up PLVD circuit and supporting reference circuitry
0 = Disables PLVD Module, powers down PLVD circuit and supporting reference circuitry
Unimplemented: Read as ‘0’
LVDL<2:0>: Low-Voltage Detection Level bits (nominal values)
111 = 4.5V
110 = 4.2V
101 = 4.0V
100 = 2.3V (default)
011 = 2.2V
010 = 2.1V
001 = 2.0V
000 = Reserved
