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

The "pulse output stop ag bit" of special elements can be monitored, and the pulse output status can be
viewed. The ag bit is set during pulse output and is automatically reset when output is nished. See the
following table.

2) Acceleration/deceleration is not supported.
3) The output pulse frequency can be increased or decreased during instruction execution.
The special ag does not need to be set. See the following gure.
