I'm evaluating the instantaneous current readings for fuel gauge BQ27742-G1 as outlined in section 4.2.14 of the reference manual by first reading the voltage (reg 0x08 and 0x09) and then reading the simultaneous current (reg 0x70 and 0x71). I've written some software that continuously reads these values and outputs them to a console. When I change the load the current readings take around 2 seconds to update, not the 125ms as documented in the TRM. I've read the manual and cannot figure out why this conversion time is so long. Any help is greatly appreciated.
4.2.14 SimultaneousCurrent(): 0x70 and 0x71
UNSEALED and SEALED Access: This is the current measured across the faster 125-ms conversion
window that is synchronized with the Voltage() measurement. It allows a more instantaneous reporting of
measured current vs traditional 1-second conversions in AverageCurrent().
