<p class="BODYTEXT">
 This command code is used in the SDLIB_IssueConfig() API.  The command
          issues CMD59 to disable SPI-CRC checking and requests the host controller 
          driver to stop checking the CRC. This is typically used in systems where 
          CRC checking is not required and performance is improved if the CRC checking
          is ommitted (i.e. SPI implementations without hardware CRC support).
