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).
