BATMONPD: Battery Monitor Power-Down bit
If battery monitor is working and battery voltage drops below the threshold by BATMON<4:0>, then
WARNIF is set.
1 = Battery monitor is OFF
0 = Battery monitor is working
BATMON<4:0>: Battery Monitor Threshold Field bits
VTHRESHOLD = 3.6 - 0.071 * BATMON<4:0> (V)
