When the Power switch is turned on, the Power LED shines.
Setting an enable signal of level shifter of HOST IF.
When the other HOST is used, remove the jumper cap from pins.
For details, please refer to the "3.1.2 HOST IF setting jumper".
Please always the jumper cap is placed on pins.
Power supply switch of SDK board.
ON: A power supply is supplied to the SDK board.
OFF: A power supply is not supplied to the SDK board.
Reset switch for ML630Q791.
Setting to update the firmware of the SDK board.
When the firmware of the SDK board is updated, the jumper cap is
placed on pins. Usually the jumper cap is not placed on pins.
When you use the other host, connect the other host to the HOST IF
connector.
Connect a debugger supporting the Cortex™-M0. (*1)
