Reading Status (C = 0001 hex)
If C is 0001 hex, PRV(881) reads status as shown in the following table.

Reading the Results of Range Comparison (C = 0002 hex)
If C is 0002 hex, PRV(881) reads the results of range comparison and stores it
in D as shown in the following diagram.

Reading the High-speed Counter Output Frequency (C = 0003 hex)
If C is 0003 hex, PRV(881) reads the output frequency of high-speed counter
0 in Hz and stores it in D and D+1. The value will be between 0000 0000 and
0001 86A0 hex (0 and 100,000). Even if the output frequency exceeds
100 kHz, the maximum value, 0001 86A0 hex, will be stored.
