POINT
The file size has the minimum unit. ( Section 5.4.4)
The occupied memory capacity may be greater than the actual file size.
Note that as the number of files rises, the difference between the occupied
memory capacity and actual file size increases.
Remark
Refer to the sections above for details of the selection, applications, procedures
and precautions for the standard ROM wiring methods.
(5) How to use the program stored in the standard ROM
Since operation cannot be executed by the program stored in the standard ROM, use
