Processing details
Specify the number of the function to be started or stopped in (s1), the bit of the channel to be started in (s2), and the bit of the
channel to be stopped in (s3).
The following table shows the function numbers which can be specified in (s1).
*1 When high-speed counter (function number: 0) is stopped during function operation, the function continues to operate, but nothing will
be processed.
*2 When multi-output high-speed comparison table (function number: 30) is stopped, high-speed counter of the same ch is also stopped.
The following table shows the values which can be specified in (s2) and (s3) for each function number.
Function number 0
The counting start and stop of a high-speed counter can be controlled for each channel of high-speed counter.
Ex.
To start CH3, set 04H in (s2). To stop it, set 04H in (s3).
To start CH1, CH4, and CH5, set 19H in (s2). To stop them, set 19H in (s3).
To start CH1 and CH4 and to stop CH5, set 09H in (s2) and set 10H in (s3).
