CAT5259
INSTRUCTION AND REGISTER DESCRIPTION
Slave Address Byte
The first byte sent to the CAT5259 from the
master/processor is called the Slave Address Byte. The most
significant four bits of the slave address are a device type
identifier. These bits for the CAT5259 are fixed at 0101[B]
(refer to Figure 8).
The next four bits, A3 A0, are the internal slave address
and must match the physical device address which is defined
by the state of the A3 A0 input pins for the CAT5259 to
successfully continue the command sequence. Only the
device which slave address matches the incoming device
address sent by the master executes the instruction. The A3
A0 inputs can be actively driven by CMOS input signals
or tied to VCC or VSS.
Instruction Byte
The next byte sent to the CAT5259 contains the
instruction and register pointer information. The four most
significant bits used provide the instruction opcode I3 I0.
The R1 and R0 bits point to one of the four data registers of
each associated potentiometer. The least two significant bits
point to one of four Wiper Control Registers. The format is
shown in Figure 9.
