Attempts to write read-only commands cause the CML: invalid command (IVC) fault condition, the TPS546D24S responds as follows:
PHASE Behavior
When PHASE = FFh, READ_VIN returns the PVIN voltage of the Loop Controller device.
When PHASE != FFh, READ_VIN returns the PVIN voltage of the device assigned to the current PHASE.
