(clear SI without writing new data
to SMB0DAT).
Acknowledge received byte;
Read SMB0DAT.
Send NACK to indicate last byte,
and send STOP.
Send NACK to indicate last byte,
and send STOP followed 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 Mas-
ter Transmitter Mode (write to
SMB0DAT before clearing SI).
