（２） User Mode
[Overview]
Mode that activates the internal ROM (flash) of the microcontroller mounted in the
microcontroller. Operation starts when the CPU obtains reset vector from the flash memory.
Setting the MD0 pin of the microcontroller to “L” level switches to this mode.
[Setting Method]
Insert the jumper for switching modes of the microcontroller in the silk notation “MD0L” side.
The Operating Mode off the microcontroller is decided after releasing power on reset,
low-voltage detection reset and INITX pin input reset. When selecting this mode, set to USB
function by switching USB host function of the microcontroller.
