25.4 ROM Correction Usage Example
as follows.
426
The example of ROM correction when the instruction at address 1000H “ADD A, #1” is changed to “ADD A, #2” is
(1) Branches to address F7FDH when the preset value 1000H in the correction address register matches the fetch
(2) Branches to any address (address F702H in this example) by setting the entire-space branch instruction (BR
(3) Returns to the program of the internal flash memory after executing the substitute instruction ADD A, #2.
