Brownout voltage in 25mV steps for the DCDC_4P2 pin.
0b00000 : 3.6V
..
0b11111 : 4.375V
Reserved.
Sets the trip point for the comparison between the DCDC_4P2 and BATTERY pin. When the comparator
output is high then, the switching converter may use the DCDC_4P2 pin as the source for the switching
converter, otherwise it will use the DCDC_BATT pin.
0b00000 DCDC_4P2 pin >= 0.85 * BATTERY pin
0b00001 DCDC_4P2 pin >= 0.86 * BATTERY pin
0b11000 DCDC_4P2 pin >= BATTERY pin (default)
0b11111 DCDC_4P2 pin >= 1.05 * BATTERY pin
