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 Pulse Output or High-speed Counter Frequency (C = 00
If C is 00@3 hex, PRV(881) reads the frequency being output from pulse output 0 or 1 or the frequency
being input to high-speed counter 0 and stores it in D and D+1.
0000 or 0001 hex (Reading the frequency of pulse output 0 or 1)
0000 0000 to 0001 86A0 hex (0 to 100,000)
0010 hex (Reading the frequency of high-speed counter 0)
Counter input method: Any input method other than 4 differential phase mode:
Result = 00000000 to 000186A0 hex (0 to 100,000)
Note If a frequency higher than 100 kHz has been input, the output will remain at the maximum value of 000186A0
hex.
Counter input method: 4 differential phase mode:
Result = 00000000 to 00030D40 hex (0 to 200,000)
Note If a frequency higher than 200 kHz has been input, the output will remain at the maximum value of
00030D40 hex.
