The simplest format for a PMBus write is direct format. After the start condition [S], the target chip address is sent, followed by an eighth bit indicating a write. TPS549B22 then acknowledges that it is being addressed, and the controller responds with an 8 bit register address byte. The target acknowledges and the controller sends the appropriate 8-bit data byte. Once again the target acknowledges and the controller terminates the transfer with the stop condition [P].
