6. SERIAL CONTROL REGISTERS
The Pin column lists the affected pin number and the @PowerUp column gives the default state at
true power up. "Command Code" byte and "Byte Count" byte must be sent following the
acknowledge of the Address Byte. Although the data (bits) in these two bytes are considered "don't
care", they must be sent and will be acknowledge. After that, the sequence described below
(Register 0, Register 1, Register 2, ....) will be valid and acknowledged.
Bytes sequence order for I

C controller :
Clock Address
A(6:0) & R/W
Ack
8 bits dummy
Command code
Ack
8 bits dummy
Byte count
Ack
Byte0,1,2...
until Stop
Set R/W to 1 when Read back”, the data sequence is as follows :
Clock Address
A(6:0) & R/W
Ack
Byte 0
Ack
Ack
Byte2, 3, 4...
until Stop
