Quick Commands (Figure 25-2) received by the PMBus module in slave mode require a simple acknowledgment of the received device address. In automatic address acknowledge mode, the module processes the quick command without firmware interaction. Upon receipt of the end of message, the firmware has the option to read the received address in the PMBHSA register. In manual address acknowledge mode, the address is acknowledged by writing to the PMBACK register.
