(7) RESET switch
This switch initializes the internal circuits of this board and feeds a reset signal to the ICE.
(8) External part connecting socket
Unused
(9) CLK and PRG switch
If power to the ICE is shut down before circuit data downloading is complete, the circuit configuration
in this board will remain incomplete, and the debugger may not be able to start when you power on the
ICE once again. In this case, temporarily power off the ICE and set CLK to the 32K position and the PRG
switch to the Prog position, then switch on power for the ICE once again. This should allow the debug-
ger to start up, allowing you to download circuit data. After downloading the circuit data, temporar-
ily power off the ICE and reset CLK and PRG to the LCLK and the Norm position, respectively. Then
power on the ICE once again.
(10) IOSEL2
When downloading circuit data, set IOSEL2 to the "E" position. Otherwise, set to the "D" position.
(11) VC5
