ALRM_en: fuel gauge alarm enable
 0: disabled
 1: enabled (default)
GG_RUN: fuel gauge operative mode
 0: standby (default). Registers are frozen, fuel gauge in standby
 1: running
LPM_dis: low power mode disable (set this bit to program battery charger/OTG
configuration registers and enable OTG function when USB input is not plugged and
GG_RUN = 0)
 0: low power mode enabled (default)
 1: low power mode disabled
OTG_en: OTG boost enable bit
 0: disabled (default)
 1: enabled

IODATA: IRQn pin status
Read:
 0: IRQn pin is low
 1: IRQn pin is high
Write:
 0: forces IRQn pin low
 1: IRQn pin is driven by interrupt logic
BAT_Fail: battery removal or battery UVLO detection bit. Write 0 to clear
 0: battery connected
 1: battery removed or UVLO
POR_Det: power-on reset detection bit. Write 1 to force a soft reset (self-clearing)
 0: no POR event occurred
 1: POR event occurred
ALRM_SOC: low SOC alarm
 0: SOC OK
 1: low SOC
