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_IOUT returns the total current for the stack of devices supporting a single output.
When PHASE != FFh, READ_IOUT returns the measured current of the device assigned to the current PHASE.
