12.5 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.
Note: Microchip Technology does not recom-
mend code protecting windowed devices.
12.6 ID Locations
Five memory locations (200000h - 200007h) are desig-
nated as ID locations, where the user can store check-
sum or other code identification numbers. These
locations are accessible during normal execution
through the TBLRD instruction or during program/
verify. The ID locations can be read when the device is
code protected.

12.7 In-Circuit Serial Programming
PIC18F010/020 microcontrollers can be serially pro-
grammed while in the end application circuit. This is
simply done with two lines for clock and data, and two
other lines for power and ground. This allows custom-
ers 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 firmware to be
programmed.
