ation, Port 3 data inputs, or T
disabled, freeing the reference input (P33) for use as IRQ1 and/or P33 input.
The comparator requires two NOPs to be stable after setting the enable bit.
ZiLOG recommends that interrupts IRQ0, IRQ1, and IRQ2 be disabled before set-
ting the enable bit. After enabling the comparator, IRQ0, IRQ1, and IRQ2 should
be cleared prior to re-enabling the interrupts. ZiLOG also recommends clearing
these interrupts when disabling the comparator.
To emulate the P32 rising edge digital interrupt the emulator must be modified in
the following way:
1. Connect P32 by soldering a wire jumper from either emulation socket (P3, pin
2. Connect 74HCT04 U27 pin 2 by soldering a wire jumper from U27 pin 2 to P30
