3.4 Self-diagnostic Program (t88112)
3.4.1 Outline of t88112
t88112 is a self-diagnostic program to check the
operation of the hardware tool ICE that is used for
program debugging of the S1C88 Family.
Perform a self-diagnostic of the ICE and Peripheral
Circuit Board periodically using this program
when using the ICE and the Peripheral Circuit
Board for debugging.
3.4.2 File configuration
(1) Program data HEX file (t88112.psa)
(2) Function option HEX file (t88112.fsa)
(3) Function option document file (t88112.fdc)

(DEVELOPMENT SOFTWARE TOOL FOR S1C88112)
Check using the VDC0–2, OSCC, LCDC, CMP0ON, CMP1ON, SVDON and HVLD LEDs on the Peripheral Circuit
Board. If the below light statuses are verified following system reset, it is normal. The cycle count indicates a 1 second
interval and the light status of the below LED changes every second. When it returns to 1 after 20, it then repeats the cycle
again.
This is the main unit of the self-diagnostic
program generated by the fil88112 and in which
FFH is filled in the unused area of the internal
ROM and the system code is set to the system
reserved area of the S1C88112.
This is the file generated by the fog88112 to set
the mask option into the ICE and the Peripheral
Circuit Board, and is used at self-diagnosis.
This is the document file generated by the
fog88112 and the setting contents of the func-
tion option HEX file mentioned above are
described.

3.4.3 Operation procedure
After installing the Peripheral Circuit Board into
the ICE, self-diagnosis of the ICE and the
Peripheral Circuit Board can be done by the
following operating test.
For the following operating test, the self-diagnostic
program (t88112.psa) and the function option HEX
data (t88112.fsa) in this package are used.
Perform the below operations with the ICE.
Execute by reading the self-diagnostic program
(t88112.psa) and the function option HEX data
(t88112.fsa) into the ICE.
Please refer the ICE help file for loading, execution.
