Note 1: Do not allocate the above program to the address from 0x0000 through 0x17FF in the code area of the
flash memory. If the area is set as BAREA="1", it changes from the flash memory area to the BOOTROM
area, so that the program will not function properly and the microcontroller may malfunction.
Note 2: It is not necessary to add DI instruction to disable interrupt maskable enable flag (IMF) for above sample pro-
gram, because the support program has it. However, the support program does not include EI instruction. En-
able IMF after finishing all above process, if you use interrupt process.
