Bit 2—User Branch Error Detect (BR): Returns the check result whether the specified user
branch destination address is in the area other than the storage area of the programming/erasing
program which has been downloaded .

(3) Programming Execution
When flash memory is programmed, the programming destination address on the user MAT must
be passed to the programming program in which the program data is downloaded.
1. The start address of the programming destination on the user MAT is set in general register
ER1 of the CPU. This parameter is called FMPAR (flash multipurpose address area
parameter).
Since the program data is always in 128-byte units, the lower eight bits (MOA7 to MOA0)
must be H'00 or H'80 as the boundary of the programming start address on the user MAT.
2. The program data for the user MAT must be prepared in the consecutive area. The program
data must be in the consecutive space which can be accessed by using the MOV.B instruction
of the CPU and is not the flash memory space.
When data to be programmed does not satisfy 128 bytes, the 128-byte program data must be
prepared by embedding the dummy code (H'FF).
The start address of the area in which the prepared program data is stored must be set in
general register ER0. This parameter is called FMPDR (flash multipurpose data destination
area parameter).
