C Communication Timing Diagram
Acknowledge Bit
Oneoftheslavedevicegeneratesanacknowledgesignal,
when the slave address is matched. The master device
can check this acknowledge bit to know if the slave device
accepts the calling address. If no acknowledge bit, the
mastermustsendaSTOPbitandendthecommunication.
When the I
2
C Bus status register bit 6 HAAS is high, it
means the address is matched, so the slave must check
SRW as a transmitter (set HTX) to 1 or as a receiver
(clear HTX) to 0 .
Data Byte
The data is 8 bits and is sent after the slave device has
acknowledges the slave address. The first bit is MSB
and the 8th bit is LSB. The receiver sends the acknowl-
byte data. If the transmitter checks and there s no ac-
knowledge signal, then it release the SDA line, and the
master sends a STOPsignal to release the I
2
C Bus. The
data is stored in the HDR register. The transmitter must
write data to the HDR before transmit data and the re-
ceiver must read data from the HDR after receiving
data.
