APPENDIX A:
The following are the list of enhancements over the
PIC16C5X microcontroller family:
1.
2.
3.
4.

7.
8.
9.
10. Wake-up from SLEEP through interrupt is
11. Two separate timers, Oscillator Start-up Timer
12. PORTB has weak pull-ups and interrupt-on-
13. Timer0 clock input, T0CKI pin is also a port pin
14. FSR is made a full 8-bit register.
15. “In-circuit programming” is made possible. The
16. PCON status register is added with a Power-on
17. Code protection scheme is enhanced such that
18. PORTA inputs are now Schmitt Trigger inputs.

Instruction word length is increased to 14 bits.
This allows larger page sizes both in program
memory (4K now as opposed to 512 before) and
register file (up to 128 bytes now versus 32
bytes before).
A PC high latch register (PCLATH) is added to
handle program memory paging. PA2, PA1, PA0
bits are removed from STATUS register.
Data memory paging is slightly redefined.
STATUS register is modified.
Four new instructions have been added:
RETURN
Two instructions
phased out although they are kept for
compatibility with PIC16C5X.
OPTION
addressable.
Interrupt capability is added. Interrupt vector is
at 0004h.
Stack size is increased to 8 deep.
RESET vector is changed to 0000h.
RESET of all registers is revised. Three different
RESET (and wake-up) types are recognized.
Registers are reset differently.

Preliminary
APPENDIX B:
To convert code written for PIC16C5X to PIC16C55X,
the user should take the following steps:
1.
2.
3.
4.
5.
Remove any program memory page select
operations (PA2, PA1, PA0 bits) for
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 data memory 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 0000h.
