Dear team:

In the PMBus group command format, what is the number of bytes sent by the master device to the slave device? (As shown in the figure below, there is only an ellipsis after it)

Best regards

    It sends command byte + 2 bytes

    Please check pg.20 group command section in PMBUS_COMMS_STACK_UG.pdf
