If the code protection bit(s) have not been pro-
grammed, the on-chip program memory can be read
out for verification purposes.
13.10
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.
For ROM devices, these values are submitted along
with the ROM code.
13.11
The PIC16CXX 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
holding pins RB6 and RB7 low while raising the MCLR
(V
tion). RB6 becomes the programming clock and RB7
becomes the programming data. Both RB6 and RB7
are Schmitt Trigger inputs in this mode.
After reset, to place the device in program/verify mode,
the program counter (PC) is at location 00h. A 6-bit
command is then supplied to the device. Depending on
the command, 14-bits of program data are then sup-
plied to or from the device, depending if the command
was a load or a read. For complete details of serial pro-
gramming, please refer to the PIC16C6X/7X Program-
ming Specifications (Literature #DS30228).
