Hi, gurus:

PMBSTS EOM bit indicate message still in progress or in idle state.

Is EOM a byte message or a electrical signal like start condition?

How module know there is no more byte comming from master so it can set EOM active?

Chen,

PMBus module sets EOM bit when it sees STOP condition generated.

Regards,

Manoj

Just wondering the C28x PMBus Communication Stack User Guide 5.2.9 Receive Byte section example:

EOM=1 happened with NACK =1 is wrong, right?

The diagram needs to be corrected, EOM bit doesn't get set on NACK. It should get set on STOP condition.
