3.3 Top Panel (LEDs)
These LEDs indicate power on and debugging statuses.
• POWER (green)
This LED starts blinking immediately after the ICDmini Ver. 3.0 is connected to the host computer. It changes
to lighting when the communication between the ICDmini Ver. 3.0 and the host computer is established.
• EMU (red)
This LED lights to indicate that the target MCU has entered DEBUG mode when the connection between the
host computer, the ICDmini Ver. 3.0, and the target system is established.
When the debugger on the host computer issues an instruction to execute the target program, this LED starts
blinking to indicate that the program on the target system is being executed. When the power supply of the
target system is off or the target system is not connected to the ICDmini Ver. 3.0, this LED is turned off.
However, once this LED starts blinking by executing the target program, it continues blinking even if the power
supply of the target system is turned off or the target system is disconnected after that.
