APPENDIX
PERIPHERAL CIRCUIT BOARDS FOR S1C63808
This section describes how to use the Peripheral Circuit Boards for the S1C63808 (S5U1C63000P1),
which provide emulation functions when mounted on the debugging tool for the S1C63 Family of 4-bit
single-chip microcomputers, the ICE (S5U1C63000H1/S5U1C63000H2).
This description of the S1C63 Family Peripheral Circuit Board (S5U1C63000P1) provided in this docu-
ment assumes that circuit data for the S1C63808 has already been downloaded to the board. For informa-
tion on downloading various circuit data, please see Section A.3. Please refer to the user’s manual
provided with your ICE for detailed information on its functions and method of use.

This control allows you to vary the power supply voltage artificially in order to verify the operation of
the power supply voltage detect function (SVD).
(3) Register monitor LEDs
These LEDs correspond one-to-one to the registers listed below. The LED lights when the data is logic
"1" and goes out when the data is logic "0".
