DEVICE ADDRESSING
Following a start condition, the master must output a
slave address byte. The first four bits of the slave
address byte specify access to the CCR. Slave bits
1101 access the CCR.
Bit 3 through Bit 1 of the slave byte specify the device
select bits. These are set to 111.
The last bit of the slave address byte defines the oper-
ation to be performed. When this R/W bit is a one, then
a read operation is selected. A zero selects a write
operation. Refer to Figure 12.
After loading the entire slave address byte from the
SDA bus, the device compares the device identifier and
device select bits with 1101111. Upon a correct compare,
the device outputs an acknowledge on the SDA line.
Following the slave byte is a two byte CCR address.
The CCR address is either supplied by the master
device or obtained from an internal counter.
In a random read operation, the slave byte in the
“dummy write” portion must match the slave byte in the
“read” section. That is, for a random read of the clock/
control registers, the slave byte must be 1101111x in
both places.
