Output. Strobe to the external A/D converter.

Input. Signal from the external A/D converter.

Output. Multiplexes low byte of a 16-bit A/D

converter onto the 8-bit ADC bus.

Output. Multiplexes the high byte of a 16-bit A/D

converter onto the 8-bit ADC bus.

Input. Determines the 80C32's operating

frequency. When grounded, the internal 80C32

operates at 10MHz. When open, the processor

operates at 16MHz.

Output. Goes low whenever offset x08 is

addressed. For use in conjuction with Node ID

switches.

Output. Open drain.
