BQ76952: I2C Communication with PEC Not Working in BQStudio

Part Number: BQ76952
Other Parts Discussed in Thread: BQSTUDIO

Tool/software:

Dear TI Support Team,

I am trying to enable PEC for I2C communication on the BQ76952 using BQStudio. I followed the steps outlined in the EVM user guide:

  1. Set Comm Type to 0x12 (I2C with PEC) in BQStudio. (Refer to Figure 2)

  2. Send the SWAP_COM_MODE command.

  3. Restart BQStudio.

  4. Read Cell 1 Voltage (Command 0x14) to check communication.

However, I2C communication still does not include PEC, as shown in I2C waveform.

Did I miss any steps? How can I ensure that PEC is enabled in BQStudio for BQ76952?

Thanks in advance!
