PIC16C64X & PIC16C66X
APPENDIX A: ENHANCEMENTS
The following are the list of enhancements over the
PIC16C5X microcontroller family:
1.
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 le (up to 176 bytes now versus 32 bytes
before).
2.
A PC high latch register (PCLATH) is added to
handle program memory paging. PA2, PA1, PA0
bits are removed from STATUS register.
3.
Data memory paging is slightly redened.
STATUS register is modied.
4.
Four new instructions have been added:
RETURN
, RETFIE, ADDLW, and SUBLW.
Two instructions TRIS and OPTION are being
phased
out
although
they
are
kept
for
compatibility with PIC16C5X.
5.
OPTION
and
TRIS
registers
are
made
addressable.
6.
Interrupt capability is added. Interrupt vector is
at 0004h.
7.
Stack size is increased to 8 deep.
8.
Reset vector is changed to 0000h.
9.
Reset of all registers is revisited. Six different
reset (and wake-up) types are recognized.
Registers are reset differently.
10. Wake up from SLEEP through interrupt is
added.
11. Two separate timers, Oscillator Start-up Timer
(OST)
and
Power-up
Timer
(PWRT)
are
included for more reliable power-up. These
timers can be invoked selectively to avoid
unnecessary delays on power-up and wake-up.
12. PORTB has weak pull-ups and interrupt on
change feature.
13. Timer0 clock input, T0CKI pin is also a port pin
(RA4/T0CKI) and has a TRIS bit.
14. FSR is made a full 8-bit register.
15. “In-circuit programming” is made possible. The
user can program PIC16CXX devices using only
ve pins: VDD, VSS, VPP, RB6 (clock) and RB7
(data in/out).
16. PCON status register is added with a Power-on
Reset status bit (POR), a Brown-out Reset sta-
tus bit (BOR), a Parity Error Reset (PER), and a
Memory Parity Enable (MPEEN) bit.
17. Code protection scheme is enhanced such that
portions of the program memory can be
protected, while the remainder is unprotected.
18. PORTA inputs are now Schmitt Trigger inputs.
19. Brown-out Reset circuitry has been added.
APPENDIX B: COMPATIBILITY
To convert code written for PIC16C5X to PIC16CXX,
the user should take the following steps:
1.
Remove any program memory page select
operations (PA2, PA1, PA0 bits) for CALL, GOTO.
2.
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.
3.
Eliminate any data memory page switching.
Redene data variables to reallocate them.
4.
Verify all writes to STATUS, OPTION, and FSR
registers since these have changed.
5.
Change reset vector to 0000h.
