DEVICE ADDRESSING
Following a start condition, the master must output a
Slave Address Byte. 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
operation 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 7.
After loading the entire Slave Address Byte from the
SDA bus, the X1205 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 word address.
The word address is either supplied by the master
device or obtained from an internal counter. On power-
up the internal address counter is set to address 0H,
so a current address read of the CCR array starts at
address 0. When required, as part of a random read,
the master must supply the 2 Word Address Bytes as
shown in Figure 7.
In a random read operation, the slave byte in the
“dummy write” portion must match the slave byte in
the “read” section. For a random read of the
Clock/Control Registers, the slave byte must be
1101111x in both places.
