19.6. SMBus Status Decoding
The current SMBus status can be easily decoded using the SMB0CN register. In the table below, STATUS
VECTOR refers to the four upper bits of SMB0CN: MASTER, TXMODE, STA, and STO. Note that the
shown response options are only the typical responses; application-specific procedures are allowed as
long as they conform to the SMBus specification. Highlighted responses are allowed but do not conform to
the SMBus specification.

Typical Response Options
into SMB0DAT.
Set STA to restart transfer.
Abort transfer.
Load next data byte into
SMB0DAT.
End transfer with STOP.
End transfer with STOP and
start another transfer.
Send repeated START.
Switch to Master Receiver
