5.2
The checksum is calculated by summing the following:
• The contents of all code memory locations
• The Configuration Block (CFGB), appropriately
• ID locations
The Least Significant 16 bits of this sum are the
checksum.
Table 5-5 (pages 28 through 30) describes how to
calculate the checksum for each device.
TABLE 5-5:
DS39644L-page 28
CFGB80 = Byte sum of [(CW1 & 0CE1h) + (CW2 & 0FC7h) + (CW3 & 01F8h)]
CFGB60 = Byte sum of [(CW1 & 0CE1h) + (CW2 & 0FC7h) + (CW3 & 0100h)]

CW3 address is the last location – 2 of implemented program memory; CW2 is the last location – 4;
CW1 is the last location – 6.

Note:
The checksum calculation differs depend-
ing on the code-protect setting. Since the
code memory locations read out differently
depending on the code-protect setting, the
table describes how to manipulate the
actual code memory values to simulate the
values that would be read from a protected
device. When calculating a checksum by
reading a device, the entire code memory
can simply be read and summed. The
Configuration Word and ID locations can
always be read.
