Problem Title:
XC1800: The use of the CF# pin in SO20 and PC20 package is limited
Problem Description:
Urgency: Standard
General Description:
The use of the CF# pin in SO20 and PC20 packages is limited.
Solution 1:
Pin 7 is shared between D4 and CF# in the SO20 and PC20 packages.
This shared pin can only be used as CF# (CONFIG Instruction) when the
1800 is configured for serial download.
This only affects xc18512 and xc1801 devices in the SO20 and PC20
packages.
