Dan: Thanks for clearing that up. How do I read the OSC calibration info using the ProPic software.

> Dan: > > Thanks for clearing that up. How do I read the OSC calibration info using the > ProPic software. Do a normal read, and check out 1FFh (if you're using a 12C508), or 3FFh (12C509). The calibration value is stored as a MOVLW. Bits 4-7 represents the calibration value. (if reading 3CA0h), the cal. value is 'A'... -Jacob Blichfeldt KILLspamblchfldtKILLspampost3.tele.dk http://home3.inet.tele.dk/blchfldt/index.htm

The last position reads 3FFF as well and this a never used 12C509. Are there any other tests I can perform to see if the programmer is I/Oing data to the pic properly?

Well, looks like I have a bad or completely erased (w/o cal info) 12C509 as I get 3FFF for the last entry as well. I tested the programmer by sticking in a 1K resistor between GP0 and GP1 after starting the read function. From the point I stick the resistor onwards, all the data is read as 0000 which makes sense 'cause the software looks for the data right after the downward transition of the clock. So at this point, either the chip is not going into program mode or its bad. Anyway, thanks for everyones help on this.
