CHECKSUM
17.1
Theory
The checksum is calculated as the 32-bit summation of
all bytes (8-bit quantities) in program Flash, boot Flash
(except device Configuration Words), the Device ID
register with applicable mask, and the device Configu-
ration Words with applicable masks. Next, the 2’s
complement of the summation is calculated. This final
32-bit number is presented as the checksum.
17.2
Mask Values
The mask value of a device Configuration is calculated
by setting all the unimplemented bits to ‘0’ and all the
implemented bits to ‘1’.
For example, Register 17-1 shows the DEVCFG0 reg-
ister of the PIC32MX360F512L device. The mask value
for this register is:
mask_value_devcfg0
= 0x110FF00B
Table 17-1 lists the mask values of the four device Con-
figuration registers and Device ID registers to be used
in the checksum calculations.
