Thank you Melanie,

You provided the exact info I needed.I had thought about the MCLR but not using an AND to activate it. After reading your reply I used a PIC12F675 to perform the AND to trigger the MCLR on the 16F628. Works perfect !

I guess a 12F675 may be overkill for a AND gate, but I needed the timing function of it to keep MCLR low for an extended period. I am not sure about using the same 16F628 as an AND as I am using several of the I/O as digital for the main program.

Thanks again, your knowledge is appreciated,
Sam
