Hello all,
	First I want to apologize to everyone on the list. I am sorry. I know=20
that I can be an opinionated, stubborn, know it all. My intent is not to=20
annoy, irritate, or make anyone mad. I'm just trying to learn, help, and=20
have fun. So please forgive me and tolerate my personally. If I irritate=20
you or get out of line please just tell me? It won't bother me at all.=20
I'm trying to be a good member.
     I have decided to switch over to a 16F690 because it has more pins.=20
In MpSim I can see the pins switching but in real life it isn't=20
happening. The reset pin is on RC1, pin 15. The Gate is on RC0, pin 16.=20
DP1 is on RC3, pin 7. Help! Please! I'm not worried about the proper=20
timing at this point. I just want to get those three pins working. The=20
crystal is running at about 16MHz.
     I have read the datasheet and done research on the Internet. I=20
still can't get it.
Thanks,
rich!

Here is the listing:
