Value

R/W Description

7 to 3 ⎯ ⎯ ⎯ Unused

Return 0

2 BR ⎯ R/W 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

1 FQ ⎯ R/W 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

0 SF ⎯ R/W Success/Fail

Indicates whether initialization is completed normally.

0: Initialization is ended normally (no error)

1: Initialization is ended abnormally (error occurs)

(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 must be stored in a general

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.

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 in other than the flash memory space.
