The HMSC bundles a sample application (APL) intended for switch operation on the board such as RX62N RSK.
After enumeration, the process executes the file Write/Read operation on the connected USB mass storage device
Explanations for APL processes are provided below.
• Press SW on RX62N RSK after configuration is completed, to write 512-byte 'a' data to the "hmscdemo.txt" file
(Write process, 1 time).
• Press SW after the above process, to read the data in" hmscdemo.txt" (Read process, loop). During the Read process,
each time the device is read 100 times, LED0~3 on RX62N RSK light up in sequence.
