Section 19 Flash Memory (0.18-µm F-ZTAT Version)
For details on the programming procedure, see section 19.4.2, User Program Mode.
(a)
This parameter stores the start address of the programming destination on the user MAT.
When the 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 the FPFR parameter.
(b) Flash multipurpose data destination area parameter (FMPDR: general register ER0 of
This parameter stores the start address of the area which stores the data to be programmed in the
user MAT. When the storage destination of the program data is in flash memory, an error occurs.
The error occurrence is indicated by the WD bit in the FPFR parameter.

Description
These bits store the start address of the programming
destination on the user MAT. Consecutive 128-byte
programming is executed starting from the specified start
address of the user MAT.
Therefore, the specified programming start address
becomes a 128-byte boundary and the MOA6 to MOA0
bits are always 0.
Description
These bits store the start address of the area which
stores the program data for the user MAT. Consecutive
128-byte data is programmed to the user MAT starting
from the specified start address.
