PIC10F200/202/204/206
5.0
For the PIC10F200/202/204/206, once code protection
is enabled, all program memory locations, 0x040-
0x0FE (F200/204) and 0x040-x1FE (F202/206) inclu-
sive, read all ‘0’s. Program memory locations, 0x000-
0x03F, 0x0FF (F200/204) and 0x1FF (F202/206), are
always unprotected. The user ID locations, backup
OSCCAL locations, and the Configuration Word read
out in an unprotected fashion. It is possible to program
the user ID locations, backup OSCCAL locations and
the Configuration Word after code-protect is enabled.
5.1
It is recommended that the following procedure be
performed before any other programming is attempted.
It is also possible to turn code protection off (CP = 1)
using this procedure. However, all data within the pro-
gram memory will be erased when this procedure is
executed, and thus, the security of the code is not
compromised.

Embedding Configuration Word
and User ID Information in the
Hex File
ERA
To allow portability of code, the program-
mer is required to read the Configuration
Word and user ID locations from the hex
file when loading the hex file. If Configura-
tion Word information was not present in
the hex file, then a simple warning
message may be issued. Similarly, while
saving a hex file, Configuration Word and
user ID information must be included. An
option to not include this information may
be provided.
Microchip Technology Incorporated feels
strongly that this feature is important for
the benefit of the end customer.

Checksum is calculated by reading the contents of
the PIC10F200/202/204/206 memory locations and
adding up the opcodes up to the maximum user
addressable
PIC10F202/206). Any Carry bits exceeding 16 bits
are neglected. Finally, the Configuration Word
(appropriately masked) is added to the checksum.
Checksum computation for the PIC10F200/202/204/
206 is shown in Table 5-2.
The checksum is calculated by summing the following:
• The contents of all program memory locations
• The Configuration Word, appropriately masked
• Masked user ID locations (when applicable)
The Least Significant 16 bits of this sum is the
checksum.
The following table describes how to calculate the
checksum for each device.
Note:

CHECKSUM
The checksum calculation differs depend-
ing on the code-protect setting. The Con-
figuration Word and user ID locations can
always be read regardless of the code
protect settings.
