I am currently programming an STC3100 trying to read battery capacity. I am successfully able to read temperature, current, and voltage, however the value for the gas gauge battery capacity is either 0x0000 or 0xFFFF. I do not understand why. I have followed the datasheet's diagram exactly. What could my issue be?

Here's a link to the datasheet: https://www.st.com/resource/en/datasheet/stc3100.pdf

Note that the value of Rcg is 0.050 ohms.

These are the only following writable registers for the device: enter image description here
