Can anyone tell me why RA4 is an "open drain" output when all the other PORTA pins are "full output drivers"? It took me a while to figure that one out, for a while I thought I had configured timer0 wrong. Also, it takes a long time for the Picstart Plus to program the entire code space of the 16F877. Is there a workaround? Am I doing something wrong with my serial port? Can I set my entire project and the programmer to PICF874 so it only programs the first 4k? I don't want to break my parts just trying it. I am only using a few hundred bytes at the moment while experimenting with several code ideas. I am runing Windows NT 4 and I've tried setting the serial port to the max possible rate. It seems like it can only program about 32 bytes a second, so it programs in over four minutes.
