APPENDIX S5U1C63000P MANUAL (PERIPHERAL CIRCUIT BOARD FOR S1C63158/358/P366)
(7) RESET switch
This switch initializes the internal circuits of this board and feeds a reset signal to the ICE.
(8) Monitor pins and external part connecting socket
These parts are currently unused.
(9) CLK and PRG switch
If power to the ICE is shut down before circuit data downloading is complete, the circuit configura-
tion 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 debugger to start up, allowing you to download circuit data. After downloading the circuit data,
temporarily power off the ICE and reset CLK and PRG to the LCLK and the Norm position, respec-
tively. 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
Unused.
