The system library can be used to prohibit suspension while an application is accessing the SD card,
so it can be used more safely. The system control function can be used to prohibit suspension
during SD card access, and for a fixed period after the SD card is accessed.
For details, refer to the System Library Manual.
(3) Auto Setup function
If a executable file is saved with a specific name (“Setup.exe“, ”Autorun.exe“) is saved
into ”¥CE¥ARM” on the Micro SD card, the executable file can run automatically when the card is
recognized, and on startup.
