INSTRUCTION AND REGISTER
DESCRIPTION
Instructions
SLAVE ADDRESS BYTE
The first byte sent to the CAT5419 from the master/
processor is called the Slave/DPP Address Byte. The
most significant four bits of the slave address are a
device type identifier. These bits for the CAT5419 are
fixed at 0101[B] (refer to Table 1).
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
CAT5419 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 V
CC
or V
SS
.
INSTRUCTION BYTE
The next byte sent to the CAT5419 contains the instruction
and register pointer information. The four most significant
bits used provide the instruction opcode I [3:0]. 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 two Wiper Control Registers. The format
is shown in Table 2.
