Interfacing the HCTL-2032 to an Atmel AVR 90S8535

The circuit shown in Figure 17 shows the connections be-

tween an HCTL-2032 and an Atmel AVR controller. Data

lines D0-D7 are connected to the Atmel AVR bus port.

The 8 MHz oscillators clock the Atmel AVR, whereas the

external 33 MHz oscillators clock the HCTL-2032. Figure

18 illustrates the program that interfaces with an Atmel

AVR 90S8535.
