Programming Guide for CPLL66-XXXX

Introduction

The CPLL66 uses a simple 3 wire interface to program four internal registers. See Figure 1.

There are four 24 bit registers that need to be programmed. Which register is written into is

simply controlled by Control Bits C1 and C2. Table I summarizes the Truth Table for Control

Bits C1 and C2.

Table II shows the details of the four 24 bit registers.
