TMS320F280049: PMBus: PMBCTRL: Bit 31: PMBus Mode vs. I2C Mode

Part Number: TMS320F280049

Hi,

Regarding F280049, in the TRM, table 23-12, we describe the PMBCTRL register.  Bit 31 is I2CMODE, selectable as PMBUS Mode vs. I2C Mode.  There isn't a lot of detail describing the differences.  In PMBSC bit 7, MAN_SLAVE_ACK description, there is a small tidbit.  Can someone please fully describe I2C Mode for the PMBus peripheral?

Thanks,

Eric
