Check any CALL, GOTO or instructions that
modify the PC to determine if any program
memory page select operations (PA2, PA1, PA0
bits) need to be made.
Revisit any computed jump operations (write to
PC or add to PC, etc.) to make sure page bits
are set properly under the new scheme.
Eliminate any special function register page
switching. Redefine data variables to reallocate
them.
Verify all writes to STATUS, OPTION, and FSR
registers since these have changed.
Change RESET vector to proper value for
processor used.
Remove any use of the ADDLW, RETURN and
SUBLW instructions.
Rewrite any code segments that use interrupts.
