Figure 17. Writing to the ICs
Slave Address
The ICs act as a slave transmitter/receiver. The slave
address of the ICs is:
Write Operations
Use the following procedure to write to a sequential
block of registers (Figure 17):
10000010 (0x82) for write operations
10000011 (0x83) for read operations
The least significant bit is the read/write indicator.
1)
2)
The master sends a start command.
The master sends the 7-bit slave address followed
by a write bit (0x82).
