7.4
Checksum Computation
The checksum is calculated by two different methods
dependent on the setting of the CP Configuration bit.
7.4.1
PROGRAM CODE PROTECTION
DISABLED
With the program code protection disabled, the
checksum is computed by reading the contents of the
PIC16F/LF182X and PIC12F/LF1822 program memory
locations and adding up the program memory data
starting at address 0000h, up to the maximum user
addressable location. Any Carry bit exceeding 16 bits
are ignored. Additionally, the relevant bits of the
Configuration Words are added to the checksum. All
unimplemented Configuration bits are masked to ‘0’.
EXAMPLE 7-1:
CHECKSUM COMPUTED WITH PROGRAM CODE PROTECTION DISABLED
PIC16F1827, BLANK DEVICE
EXAMPLE 7-2:
CHECKSUM COMPUTED WITH PROGRAM CODE PROTECTION DISABLED
PIC16LF1827, 00AAh AT FIRST AND LAST ADDRESS
