Hardware Work Around on the on the Z86CCP01ZEM Emulator to P32
Rising Edge Interrupt
PAD
P31
PAD
P32
P33
PAD
To emulate the P32 rising edge interrupt the emulator must be modified in the fol-
lowing 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
17) or (P2, pin 12) to 74HCT04 U27 pin 1.
on either emulator socket (P3, pin 25) or (P2, pin 18).
