setting.
1b: Enable Low Power Mode. Device in low power mode with battery only for
lowest quiescent current. The LDO is off. The PROCHOT, discharge current
monitor buffer, power monitor buffer and independent comparator are disabled.

WATCHDOG Timer Adjust
Set maximum delay between consecutive I2C write of charge voltage or charge
current command.
If device does not receive a write on the REG0x05/04() or the REG0x03/02()
within the watchdog time period, the charger will be suspended by setting the
REG0x03/02() to 0 mA.
After expiration, the timer will resume upon the write of REG0x03/02(),
REG0x05/04() or REG0x01[6:5]. The charger will resume if the values are
valid.
00b: Disable Watchdog Timer
01b: Enabled, 5 sec

IDPM Auto Disable
When CELL_BATPRESZ pin is LOW, the charger automatically disables the
IDPM function by setting EN_IDPM (REG0x00[1]) to 0. The host can enable
IDPM function later by writing EN_IDPM bit (REG0x00[1]) to 1.
0b: Disable this function. IDPM is not disabled when CELL_BATPRESZ goes
LOW. <default at POR>
1b: Enable this function. IDPM is disabled when CELL_BATPRESZ goes LOW.
