TPS650332-Q1: [Question for Phil's FAQ] CRC for TPS650332-Q1 I2C writing on the PMIC side

Tool/software:

Hi expert，

Customers want to use the PMIC for I2C configuration directly but currently they are not able to do I2C writes. Can you provide a way to configure the I2C_CRC on the PMIC side? And not from the MCU side.

Best Regards,

Winnie

    Hi Winnie,

      There is no way to configure the I2C_CRC on the PMIC side only; whenever the feature enabled, both sides need to follow the rule. 

      Also, FYI; the GPN TPS650332-Q1 is FuSa GPN which requires both I2C_CRC and CFG_CRC enabled for mass production and we strongly ask customers to have both enabled from sample phase to save time from one more sample cycle before mass production. 

    Thanks!

    Phil
