: tpu_tsm_rd_dp
: To read the desired position.
: This function has 2 parameters:
: desired position - The desired position is returned as a UINT16.
: tpu_tsm_rd_cp
: To read the current position.
: This function has 2 parameters:
: current position - The desired position is returned as a UINT16.
*tpu - This is a pointer to the TPU3 module to use. It is of
channel - This is the number of the master channel
read of the desired position can be used to drive the program.
