<p class="BODYTEXT">
 Implemented as a macro. SPI-capable cards and systems can operate in 
          non-CRC protected mode.  In this mode the host controller should ignore
          CRC fields and/or disable CRC generation when issuing command or data
          packets.  This option is useful for software based SPI mode where CRC
          should be turned off in order to reduce processing overhead.
