Hi,

Thanks Darrel for responding fast. I don't think there are banking issues. I use "CHK?RP", Banksel or sometimes and manually take care mpst of the times.

I remembered have done this (4 bit) before on a 16F676 and used button scanning on the same bus as LCD. RBIF driven, didn't have any problem. It was on a 16F676 internal osc.

Anything else ?
