Programming the Slave Address Using the Serial Bus
A-3
A.2 Programming the Slave Address Using the Serial Bus
A general call (Master issues a start condition followed by eight zeroes)
is used to address every device on the serial bus. Any device that
requires information to be supplied through this general call must
acknowledge the cycle.

General Call Address
A.2.1 Write Cycle Using the Serial Bus
The following steps describe a write cycle using the serial bus.
1.
The cycle is started by the Master issuing a start condition.
2.
The 7-bit slave address is transmitted.
3.
The R/W bit is reset to 0 and transmitted, indicating a write cycle.
4.
The addressed Slave acknowledges the reception of the slave
address by driving SDA LOW in the ACK cycle.
5.
The Master sends the 8-bit address.
6.
The addressed Slave acknowledges the reception of the address by
driving SDA LOW in the ACK cycle.
7.
The Master sends the 8-bit data.
8.
The addressed Slave acknowledges the reception of the data by
driving SDA LOW in the ACK cycle.
9.
The Master terminates the cycle by issuing a stop condition.
