Hi,
Whatever Microchip specification about ICSP is not correct. Especially i =
want to develop a programmer for Flash controllers like 16F84,16F628 and =
16F873. I could succeed in reading, writing,erasing the flash memory and =
configuration memory. Whereas if i try to protect and unprotect the chip =
i could n't. I have followed the ICSP specification to do the above =
function which is given by Microchip. But my time and effort gone waste. =
Microchip should not do this. I feel Microchip is cheating the engineers =
by giving a wrong programming spec.

With Regards,
Anbu
