Hi Jeff,
        I purchased the ICD without the Demo Board, or Header, so I
can only go by the documentation. My guess would be that to maintain
maximum flexibility they left the PIC Tx/Rx pins uncommitted. It
would have been better to have built the board with pins to jumper
the MAX232 to the PIC.
        As the parts around the MAX232 are optional and default, not
populated, uChip left those connections as an exercise for the
purchaser ;-) It would have been nice of them to mention it in
Section A.3.6 where they talk about the RS-232 Serial Port.

        I have a guestion on the operation of the ICD. How does it
know what type of chip it is programming?

        I have found that I can override the ICD Options config
settings by having them specified in the object file. As these are
the only real differences between the 'F87x chips, and the
'F84/'F628, I was hoping to program these flash chips with the ICD,
but I get the message 'no target' when I try to program one of these.
So my question, does anyone know, what the ICD does to detect the
type of chip being programmed?
