bq34z100-G1 question

You can find the SubClass and Offset numbers in the Data Memory section of bqStudio. The attached document provides examples of data flash programming.

thanks for the document.

I can talk to the chip and cross check data received with the default settings from the document.
I can read internal temperature and it is around 25C

when I read back the Pack configuration register it does not correlate with the default values. [I have not changed anything]

Thomas, one more question
I can read pack configuration from extended commands 0x3a/0x3b, but I cannot figure out what these nits mean.
the document says "This read-only command pair allows the host to read the configuration of selected features of the device
pertaining to various features"

what are the various features? what bits correspond to to what features?

The Pack Configuration bit definitions can be found on page 34 of the datasheet.

Thomas,
when I read pack config using extended commands 0x3a/0x3b I read back 0x41d9 [which is not the default value]
when I read pack config using subclass 0x40 offset 0x00 I read back 0xabd9 [which is not default value]

it i my understanding that I should read the same value with both methods. the values read back don't make sense either

Here is a clip from my Advanced Comm I2C screen where I read the Pack Configuration register. The data in the register is 09F8. The first line is using the Extended I2C commands and the data is returned in the Little Endian format. The next four lines are using the direct data flash access commands and it returns the same data without the Little Endian formatting.

The screenshot did not save in the original entry, so I added it above.
