... Checksum is calculated by reading the contents of the PIC16F59 memory locations and adding up the opcodes up to the maximum user addressable location, (e.g., 0x7FF for the PIC16F59). Any carry bits exceed- ing 16 bits are neglected. Finally, the Configuration Word (appropriately masked) is added to the check- sum ...
