When flash memory is programmed, the programming destination address and programming
data 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
2. The program data for the user MAT must be prepared in the consecutive area. The program
This parameter indicates the start address of the programming destination on the user MAT.
When an address in an area other than the flash memory space is set, an error occurs.
The start address of the programming destination must be at the 128-byte boundary. If this
boundary condition is not satisfied, an error occurs. The error occurrence is indicated by the
WA bit (bit 1) in FPFR.

R5 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.
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 R4. This parameter is called FMPDR (flash multipurpose data destination
area parameter).
For details on the programming procedure, see section 22.5.2, User Program Mode.
