9 HIGH-SPEED COUNTER INSTRUCTION
9.1 High-speed Processing Instruction
641
9

Function number 10
The measuring start and stop of the pulse density (rotation speed measurement) can be controlled for each channel of the
high-speed counter.

Function number 30
For the multi-output high-speed comparison table, specification of a channel is not required. To start the multi-output high-
speed comparison table, set 01H in (s2). To stop it, set 01H in (s3).

Function numbers 40 and 50
The measuring start and stop of pulse width measurement and PWM can be controlled for each channel.
Precautions
• When values that turn on the same channel are set for start and stop, the stop operation is prioritized.
• To start the multi-output high-speed comparison table (function number: 30), the high-speed counter must be started using
the HIOEN instruction in advance.
• The high-speed input/output instructions operate according to the following parameters.
