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.
