Part Number: TMS320F280049C
Other Parts Discussed in Thread: C2000WARE

Tool/software:

Hi team,

Can the I2C module and PMBus module of F280049C be used at the same time?
If I turn PMBus into I2C mode, is there anything I need to pay attention to?

    Hi Jimmy,

    I2C and PMBUS are two separate modules and can be used at the same time on different GPIOs. Beyond enabling/disabling I2C mode, ensure that this following field within the PMBSC register is set to 1.

    We also have this reference example: C:\ti\c2000\C2000Ware_5_05_00_00\libraries\communications\PMBus\c28\examples\28004x_pmbus_i2c_eeprom

    Best Regards,

    Aishwarya
