The developer should use this code as an example for calling the TPU TSM functions and incorporating
these calls into a final application.

/* FILE NAME: tpu_tsm_ex1.c
/* VERSION: 1.0
/*
/* DESCRIPTION: This sample program shows a simple example of a program
/* that initializes the TSM function and updates a desired position
/* varible from the CPU. The position in the current position moves most
/* efficiently to the new desired position. The table of byte variables
/* establishes the rate of speed. Advancing through the next byte step in */
/* the table will accelerate the speed of the motor. (ie. Table Stepper
/* Motor--TSM).
/* The example uses the TPU A on a master channel and up to three
/* consecutive channels. The master channel for this example is 0. With
/* channels 1, 2, and 3 as the table parameter channels.
/* The program is targeted for the MPC555 but should work on any MPC500
/* device with a TPU. For other devices the setup routines will also need */
/* to be changed.
