POINT
(1) The maximum number of bytes per write operation when writing data is fixed.
Write all the data read from the QnACPU and stored in the external device to
the designated file by dividing it into several parts by adjusting the offset
address and number of bytes written.
(2) The attribute designated during file creation, etc. is valid as the attribute of the
file to which data is written.
When writing data, treat the attribute as dummy data.
(3) When the following files are designated while the QnACPU is in operation, an
error occurs and an abnormal completion code will be returned.
• Parameter file
• Currently executing file in the built-in RAM (drive name: 00
(4) Designate the relevant values within the following range.
• Offset address:
• Number of bytes written
