** The Step Number must be offset by -1 when writing step data to the MC. Steps 1-64 will be sent with the
step number as a value of 0-63 (-1 offset).
All remaining steps of the program follow the same format and data structure as is represented for step
one above. Each step of the program is downloaded to the same registers (91 to 100). The step number
in register 91 designates the step that the data is for on each write command. Since few if any programs
will contain the maximum of 64 steps, it is only necessary to write the step data for the number steps
used in the automatic program.
Notes:
*D W Specifies write only data.
*E1
