: tpu_tsm_mov
: To activate the move and acceleration of the stepper motor.
: This function has 3 parameters:
*tpu - This is a pointer to the TPU3 module to use. It is of
channel - This is the number of the master channel
position - The new desired position for the stepper motor.

additional master channel(s) would be for another TSM function.
