SLUSCC7C July 2016 – June 2018 TPS546C23
The OPERATION command turns the device output on or off in conjunction with input from the CNTL signal. It is also used to set the output voltage to the upper or lower margin voltages. The unit stays in the commanded operating mode until a subsequent OPERATION command or a change in the state of the CNTL pin instructs the device to change to another mode.
For PWM loop slave device, which is recognized during power-up calibration, this command cannot be accessed. Any writes to this command will be ignored. An attempt to read or write this command will result in a NACK’d command, the reporting of an IVC fault, and triggering of SMB_ALERT.
