Mode Function Explanation
the status of the tappet point is ON before the tappet point is passed
in the negative direction. Otherwise, the status of the tappet point
which is read will be ON if the status of the tappet point is OFF before
the tappet point is passed in the negative direction.

Precaution
Please make sure that the cam curve is called for use by one MC_CamIn instruction at most if
DMC_CamWriteTappetValue is used to set the parameters for one tappet point in the cam curve.
If the cam curve is called by multiple MC_CamIn instructions, the tappet point to be modified which is
used in the programs will be changed when DMC_CamWriteTappetValue is used to change the
parameters of one tappet point.
