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 must be stored in a general
2. The program data for the user MAT must be prepared in the consecutive area. The program

Since the program data is always in units of 128 bytes, 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.

of the CPU and in other than the flash memory space.

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.
0: User branch address setting is normal
1: User branch address setting is abnormal
Frequency Error Detect
Returns the check result whether the specified operating
frequency of the CPU 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 is completed normally.
0: Initialization is ended normally (no error)
1: Initialization is ended abnormally (error occurs)
