Hi, Aishwarya: I have an power supply need to play master role and control other units when there is no system connect to my power supplies, and when there is a system connect to my power units, I need to change the role to slave to responce the system's command. If the PMBus module can know its own address is been called at master mode, I think change the role in real time is acceptable. But I'm not sure SLAVE_ADDR_READY can be trigger or not when in master mode? Thanks!
