Low Power Mode Enable
0b: Disable Low Power Mode. Device in performance mode with battery only.
The PROCHOT, current/power monitor buffer and comparator follow register
setting.
1b: Enable Low Power Mode. Device in low power mode with battery only for
lowest quiescent current. /PROCHOT, discharge current monitor buffer, power
monitor buffer and independent comparator are disabled. Independent
comparator can be enabled by setting either REG0X30()[14] or [13] to 1.

WATCHDOG Timer Adjust
Set maximum delay between consecutive SMBus write of charge voltage or
charge current command.
If device does not receive a write on the REG0x15() or the REG0x14() within
the watchdog time period, the charger will be suspended by setting the
REG0x14() to 0 mA.
After expiration, the timer will resume upon the write of REG0x14(),
REG0x15() or REG0x12[14:13]. The charger will resume if the values are
valid.
00b: Disable Watchdog Timer
01b: Enabled, 5 sec
10b: Enabled, 88 sec
11b: Enable Watchdog Timer, 175 sec <default at POR>

IDPM Auto Disable
When CELL_BATPRESZ pin is LOW, the charger automatically disables the
IDPM function by setting EN_IDPM (REG0x12[1]) to 0. The host can enable
IDPM function later by writing EN_IDPM bit (REG0x12[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.
