High-speed Counter/Pulse Output Instructions
872
■ Reading Status (C = 0001 hex)
If C is 0001 hex, PRV(881) reads status as shown in the following table.
Port and Operation
mode
Pulse out- The pulse
put output sta-
tus is
stored in
D.
High- The high-
speed speed
counter counter
input status is
stored in
D.
PWM(891) The
output PWM(891)
output is
stored in
D.
■ 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.

D 0 0 0 0 0 0 0 0
■ Reading Pulse Output or High-speed Counter Frequency (C = 00@3 hex)
If C is 00@3 hex, PRV(881) reads the frequency being output from pulse out-
put 0 or 1 or the frequency being input to high-speed counter 0 and stores it in
D and D+1.
