High−level Instructions
3 − 42
Description
S2 block of data stored in the data register starting from S1 is transferred into the F–ROM area specified by D.
At this time, the transferred data is handled in units of 1 block (2,048 words).

Data can be written to the F–ROM up to 10,000 times.
In order to prevent this instruction from being written to the F–ROM numerous times through erroneous
programming, it has been set up as a differential execution type of instruction (P13). When setting up the
program, however, please make sure that this instruction is not written to the F–ROM numerous times.
The number of blocks that can be written to is only one. Also, a maximum time of approximately 100 ms is
required for instruction execution. To write to multiple blocks, first divide into multiple scans.
This instruction should not be used in interrupt programs.
Flag conditions
・Error flag (R9007): Turns on and stays on when:
・Error flag (R9008): Turns on for an instant when:
− The number specified by S1 does not exist in the memory area.
− The area specified by S2 exceeds the limit of the memory area.
− The area is exceeded when blocks specified by D and subsequent
parameters are transferred.
