BQ34Z100-G1: implementing calibration on the bq34z100-G1

Part Number:BQ34Z100-G1

This is a follow up question to this question:

https://e2e.ti.com/support/power-management/f/196/t/798421

I have a couple of questions about the flowchart in the bq34110 Technical ref manual linked here:

http://www.ti.com/lit/ug/sluubf7a/sluubf7a.pdf

In section 5.3 “Enter Calibration Mode”,  The commands to enter calibration are:

1. I2CWriteWord(0x00, 0x002D, 100) // write sub command 0x002D CAL_ENABLE

2. I2CWriteWord(0x00, 0x0057, 100) // write sub command 0x0057 Question 1, what is write command 0x0057? I don’t see a command 0x0057 in the bq34z100-G1 document.

3. I2CReadBlock(0x40, 2, 100) // read 2 bytes from address 0x40 Question 2, what is read command 0x0040?

Thanks,

Doug
