Hello everyone,

I'm doing my university project using MC68HC908GP32. I've constructed the programming board for the monitor mode entry using 9.8304MHz crystal clock.

When I tried to enter the monitor mode using PROG08SZ Programmer, this is what I get (refer screenshot). As I go through the manual (Help), it said that
the problem for status 1. is most likely because "The part did not start the monitor mode security check on reset.  Signals to force monitor mode may be incorrect."

I've searched through the Help but I couldn't figure out what it is. Could anyone help me on this matter? I really really appreciate it. Attached are my screenshot of the problem and my circuit board.

Thank you.
