activated by one of the following commands:
• set_mcbsp_global_matrix
• set_mcbsp_global_rot
• set_mcbsp_global_x
• set_mcbsp_global_y
• set_mcbsp_global_matrix_list
• set_mcbsp_global_rot_list
• set_mcbsp_global_x_list
• set_mcbsp_global_y_list

changing that mode and before applying the
data by starting a Processing-on-the-fly session.
• Example: set_mcbsp_global_x
set_mcbsp_global_y combine the xy offsets in
the lower and upper half word of the
transmitted data.
set_mcbsp_global_y( Scale = 0.0 ) disables
the y offset and the latest sent data value is
used in total as x offset. Make sure to transmit
the correct x offset again.
