C bus operation
address and if a match is found, it acknowledges the identification on SDA bus during the
9
Write operation
Following the START condition the master sends a device select code with the RW bit set
to 0. The STA308A acknowledges this and the writes for the byte of internal address.
After receiving the internal byte address the STA308A again responds with an
acknowledgement.
Byte write
In the byte write mode the master sends one data byte, this is acknowledged by the Omega
DDX core. The master then terminates the transfer by generating a STOP condition.
Multi-byte write
The multi-byte write modes can start from any internal address. The master generating a
STOP condition terminates the transfer.
