TPS549D22: Pin strap for RCSP bit field

Oba

Part Number: TPS549D22

Hello

 

There is RCSP bit field in MFR_SPECIFIC_03 register.

Since Reset column of this bit field in the datasheet is “P”, it looks to be configured by pin strap.

But I can’t understand what pins are assigned to pin strap of this RCSP bit filed.

Could anybody tell me that?

 

Regards,

Oba

    Hi Oba,
    Since this is a PMBUS part, the default programmed value for RCSP is R/1 [01b] and FS is 650kHz [011b]. You can only change these values via PMBUS and perform the "Store Config to NVM" which will allow you to reboot the part and maintained the last programmed value.
    Thanks,
