PMBUS specified that NVM (default or user) stored values overwrite pin-programmed values. Setting a “1” in each bit of this register prevents DEFAULT or USER STORE values from overwriting the pin-programmed value associated that bit.

PIN_DETECT_OVERRIDE allows the user to force pin-detected values to override the user store NVM value for various PMBus commands during power-on reset and RESTORE_USER_ALL.
