Typical Action
Load SMB0DAT with Slave Address +
R/W. Clear STA.
Load SMB0DAT with Slave Address +
R/W. Clear STA.
Load SMB0DAT with data to be transmit-
ted.
Acknowledge poll to retry. Set STO +
STA.
1) Load SMB0DAT with next byte, OR
2) Set STO, OR
3) Clear STO then set STA for repeated
START.
1) Retry transfer OR
2) Set STO.
Save current data.
If only receiving one byte, clear AA (send
NACK after received byte). Wait for
received data.
Acknowledge poll to retry. Set STO +
STA.
Read SMB0DAT. Wait for next byte. If
next byte is last byte, clear AA.
Set STO.
