#27044 - RE: Port problems with AT89C52
I'm using a 11.0592 crystal between pins 18 and 19 (XTAL1 and XTAL2), it this what you are referring to as "clock?".

The reset consists of a 10uF cap in series with a 100MOhm resistor, and for the switch I'm just using a wire to sort to VPP. The cap/resistor combitionation should be enough to hold it high for 2 machine cycles.

Thanks for your quick reply.
