I am just coming up to speed on PIC microcontrollers and have a few
simple questions about the 16C(F)84 parts.

1) Why would I want to use a 16C84 rather than a 16F84? Most all of the
examples that I have seen posted are for the 16C84. Is this only because
that part was around longer, or is it a preference for the EEPROM?

2) Has anyone successfully used either an X902-ND or PX400-ND 4Mhz
resonator from DigiKey with the 16F84?

3) Can anyone confirm that David Tait's parallel port programmer works
for both parts? Can you explain what I should do differently for the
16F84?

4) Appendix A in the P16C84 datasheet says PA2, PA1 and PA0 are removed
from the status register and placed in the option register. It sure does
not look that way from the data sheet. Can anyone explain what they are
trying to say here.


Thanks
