[7] Calendar oscillator test
1) Key operation
2) Functional description
This program is used to test the calendar oscillator function.
Display:
"
–
" shows the current time.
"–" is blinking. (500ms ON and OFF)
3) Check items
Time elapsed after master reset must be displayed.
4) Test termination

printed
[8] SSP test
1)Key operation
2) Functional description
If an SSP is programmed, its contents are automatically checked and
the result is printed.
Display:
3) Check items
Check printing of the termination message.
4) Test termination
This check is terminated automatically.
The test terminates and the test No. and message is printed
In this SSP check, set the data for check in the empty area of SSP
entry REG and erase the data for check after completion of check.
Therefore SSP setting before check is not cleared.
If therefore there is no SSP entry REG remained for the SSP
check, F-print is performed to terminate the program without
check.
