Precaution during programming
Executing this instruction does not rewrite the contents of the
system ROM in the control unit. As a result, turning the power
supply off and then on again rewrites the contents of the system
registers specified by the tool software.
A value between K40 and K47 should be specified for “D1” or “D2”.
Also, the values should always be specified in such a way that D1
D2.
The values of the system registers change, so a verification error
may occur when the program is verified.
Flag conditions
・Error flag (R9007): Turns on and stays on when:
・Error flag (R9008): Turns on for an instant when:
− D1 > D2
− The specified value is outside the ranges specified for the various system
registers setting values
