You may get into a situation that transfers the contents of the EEPROM
into CMOS RAM memory. The data values (timers, counters and storage
bits/words) that were present when the EEPROM was burned will also be
transferred along with the ladder diagram.
You can use either one of two methods to inhibit operation:
MCR method - the processor is disabled for one scan before I/O update
(Figure 25.3).

JMP method - the program is jumped over once before I/O update
(Figure 25.4).
