/* ------------------------------------------------------------------------
File   : digio.h

Descr  : Include file for the Digital-I/O routines in digio.c.

History: 21JUL.00; Henk B&B; Definition.
         30NOV.00; Henk B&B; Added interrupt enable.
	 23JUL.01; Henk B&B; Share PORTA between in- and outputs;
	                     add input interrupt masks.
	 16JAN.03; Henk B&B; Ported to ATmega128.
