STC3100
Values held in consecutive registers (such as the charge value in the REG_CHARGE_LOW
and REG_CHARGE_HIGH registers) must be read with a single I2C access to ensure data
integrity. It is possible to read multiple values in one I2C access, all values will be consistent.
The charge data is coded in 2’s complement format, and the LSB value is 6.70 uV.h.
The battery current is coded in 2’s complement format, and the LSB value is 11.77 uV. In
13-bit resolution mode, the 0 bit is always set to zero. In 12-bit resolution, bits 0 and 1 are
always set to zero.
The battery voltage is coded in binary format, and the LSB value is 2.44 mV.
The temperature value is coded in 2’s complement format, and the LSB value is 0.125° C.
The temperature of 0° C corresponds to code 0.

32,768 Hz clock source:
0: auto-detect, 1: external clock
Gas gauge ADC resolution:
00:14 bits, 01:13 bits, 10:12 bits
0: no effect
1: used to calibrate the AD converters
0: standby mode. Accumulator and counter
registers are frozen, gas gauge and battery
monitor functions are in standby.
1: operating mode.
Unused
Port IO0 data status:
0 = IO0 input is low, 1 = IO0 input is high
Port IO0 data output drive:
0 = IO0 output is driven low,1 = IO0 output is open
0: no effect
1: resets the charge accumulator and conversion
counter. GG_RST is a self-clearing bit.
Set at the end of a battery current conversion
cycle. Clears upon reading.
Set at the end of a battery voltage or temperature
conversion cycle. Clears upon reading.
Power on reset (POR) detection bit:
0 = no POR event occurred,
1 = POR event occurred
Soft reset:
0 = release the soft-reset and clear the POR
detection bit, 1 = assert the soft-reset and set the
POR detection bit.
Unused
