8 / 16 page CAT5269 Doc. No. MD-2123 Rev. E 8 © 2008 SCILLC. All rights reserved. Characteristics subject to change without notice INSTRUCTION AND REGISTER DESCRIPTION SLAVE ADDRESS BYTE The first byte sent to the CAT5269 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 CAT5269 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 CAT5269 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 CAT5269 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. Data Register Selection Data Register Selected R1 R0 DR0 0 0 DR1 0 1 Figure 6.
