CAT5251
Document No. 2017, Rev. D
INSTRUCTION AND REGISTER
DESCRIPTION
DEVICE TYPE / ADDRESS BYTE
The first byte sent to the CAT5251 from the master/
processor is called the Device Address Byte. The most
significant four bits of the Device Type address are a
device type identifier. These bits for the CAT5251 are
fixed at 0101[B] (refer to Table 1).
The two least significant bits in the slave address byte,
A1 - A0, are the internal slave address and must match
the physical device address which is defined by the state
of the A1 - A0 input pins for the CAT5251 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 A1 - A0
inputs can be actively driven by CMOS input signals or
tied to V
CC
or V
SS
. The remaining two bits in the device
address byte must be set to 0.
INSTRUCTION BYTE
The next byte sent to the CAT5251 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 Table 2.
