Note:
1) The user may monitor the corresponding special register for checking current pulse position,
as shown in the following table.

You can monitor the "pulse output stop ag bit" of special elements, and view the pulse output status. This
ag bit will be set during pulse output and will be automatically reset when pulse output is nished. See the
following table.

2) Acceleration/deceleration is not supported.
3) The number of output pulses can be increased or decreased during instruction execution.
Before modifying the number of output pulses, you need to set the "pulse modication valid ag bit" (M8350,
M8370, M8390, M8410, or M8430; default value: OFF) of special elements. See the following table.
