(b) Flash pass/fail result parameter (FPFR: general register R0L of CPU)
This parameter indicates the return value of the initialization result.

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 has been downloaded.
1. The start address of the programming destination on the user MAT must be set in general
2. The program data for the user MAT must be prepared in a consecutive area. The program data

register ER1. This parameter is called the flash multipurpose address area parameter
(FMPAR).
Since the program data is always in 128-byte units, the lower eight bits (A7 to A0) must be
H'00 or H'80 as the boundary of the programming start address on the user MAT.
must be in the consecutive space that can be accessed by using the MOV.B instruction of the
CPU and in an address space other than flash memory.
When data to be programmed does not satisfy 128 bytes, 128-byte program data must be
prepared by filling in 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 the flash multipurpose data destination area
parameter (FMPDR).

Frequency Error Detect
Returns the check result whether the specified CPU
operating frequency is in the range of the supported
operating frequency.
0: Setting of operating frequency is normal
1: Setting of operating frequency is abnormal
Success/Fail
Indicates whether initialization has ended normally or
not.
0: Initialization has ended normally (no error)
1: Initialization has ended abnormally (error occurred)
