Programming Guide for CPLL66-XXXX
Introduction
The CPLL66 uses a simple 3 wire interface to program four internal registers. See Figure 1.
Figure 1. Timing Diagram
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.
