Serial Control Registers
NOTE:
The Pin# column lists the relevant pin number where applicable. The @Pup column gives the default state at
power up.
Following the acknowledge of the Address Byte, two additional bytes must be sent:
1)
Command Code
byte, and
2)
Byte Count
byte.
Although the data (bits) in these two bytes are considered
don
t care
; they must be sent and will be acknowledged.
After the Command Code and the Count bytes have been acknowledged, the sequence described below (Byte 0, Byte 1,
and Byte 2) will be valid and acknowledged.
