The ADC whose conversion rate is 25 µsec is operated at intervals of 400 µsec 32 times and
from the data thus obtained, the maximum and minimum values are deleted.
After that, the average value is calculated and output to the main CPU as a 16-bit A/D value.
In case of simultaneous measurement at two wavelengths, the above operation is conducted
while changing the MPX at intervals of 200 µsec and two 16-bit A/D values separately
calculated in H8 for the main and sub wavelengths are output.
