{ Purpose:   The purpose of this procedure is to stop the
{            collection of SPI data. The SPI environment must be
{            reserved by the calling task and the collection of
{            SPI data must have started prior to the call to this
{            procedure. The collection of the data may have stopped
{            prior to the call to this procedure. This could be from
{            either a system error or the number of samples collected
{            has been reached.
