Functional description
6.7
Timing diagram in run mode
Figures 6 and 7 describe the timing diagrams of the STC3105. It is assumed that the gas
gauge has been reset with GG_RST before GG_RUN=1.

The voltage is measured first after GG_RUN bit is set to 1. The charge accumulator is
updated every 500 ms using the last current value. The measurement cycles can be
interrupted by setting GG_RUN=0 and the current conversion cycle is aborted.
