Program Verification/Code Protection
If the code protection bit(s) have not been pro-
grammed, the on-chip program memory can be read
out for verification purposes.
9.10
ID Locations
Four memory locations (2000h - 2003h) are designated
as ID locations, where the user can store checksum or
other code identification numbers. These locations are
not accessible during normal execution, but are read-
able and writable during program/verify. It is recom-
mended that only the 4 least significant bits of the ID
location are used.
9.11
In-Circuit Serial Programming
PIC16C433 microcontrollers can be serially pro-
grammed, while in the end application circuit. This is
simply done with two lines for clock and data, and three
other lines for power, ground and the programming
voltage. This allows customers to manufacture boards
with unprogrammed devices, and then program the
microcontroller just before shipping the product. This
also allows the most recent firmware or a custom firm-
ware to be programmed.
The device is placed into a Program/Verify mode by hold-
ing the GP1 and GP0 pins low, while raising the MCLR
(VPP) pin from VIL to VIHH (see programming specifica-
tion). GP1 (clock) becomes the programming clock and
GP0 (data) becomes the programming data. Both GP0
and GP1 are Schmitt Trigger inputs in this mode.
After RESET, and if the device is placed into Program-
ming/Verify mode, the program counter (PC) is at loca-
tion 00h. A 6-bit command is then supplied to the
device. Depending on the command, 14-bits of pro-
gram data are then supplied to or from the device,
depending if the command was a load or a read. For
complete details of serial programming, please refer to
the PIC16C433 Programming Specifications.

Note 1: XT, HS or LP oscillator mode assumed.
2: TOST = 1024TOSC (drawing not to scale). This delay will not be there for INTRC and EXTRC osc mode.
3: GIE = ’1’ assumed. In this case, after wake-up, the processor jumps to the interrupt routine. If GIE = ’0’, execution will continue in-line.
4: CLKOUT is not available in XT, HS or LP osc modes, but shown here for timing reference.
Note:
Microchip does not recommend code pro-
tecting windowed devices.
