Three LEDs are included as status display devices.
(1) RESET_IN
(2) RESET_OUT
(3) V
(4) X1 pin
(5) X2 pin
(6) FLMD0
(7) 5 V_CHK
(8) GND
This is the target’s reset input signal.
This is a reset signal output to the target device.
An interface output signal is generated when the target system’s V
This is an output signal that is used to supply the clock.
This is a bidirectional signal used for data communications.
This is an output signal used to overwrite the target device’s flash memory.
This is a power supply pin for the self-check board only.
Up to 50 mA can be supplied via this pin. However, since power is being supplied via the USB bus, a voltage
drop occurs when voltage is drawn via this pin. Therefore, do not supply voltage to the target device from this
pin.
This is a GND pin.
