Typical Response Options
Acknowledge received byte;
Read SMB0DAT.
Send NACK to indicate last
byte, and send STOP.
Send NACK to indicate last
byte, and send STOP fol-
lowed by START.
Send ACK followed by
repeated START.
Send NACK to indicate last
byte, and send repeated
START.
Send ACK and switch to
Master Transmitter Mode
(write to SMB0DAT before
clearing SI).
Send NACK and switch to
Master Transmitter Mode
(write to SMB0DAT before
clearing SI).
No action required (expect-
ing STOP condition).
Load SMB0DAT with next
data byte to transmit.
No action required (expect-
ing Master to end transfer).
No action required (transfer
complete).
