Interfacing the HCTL-2032 to an Atmel AVR 90S8535
The circuit shown in Figure 17 shows the connections between 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.
