+
+  @return: SDIO Status
+
+  @notes:     This command code is used in the SDLIB_IssueConfig() API.  The command
+          alters the card's bus mode (width and clock rate) to a driver specified
+          value.  The driver must read the current bus mode flags, modify if necessary
+          and pass the value in the SDCONFIG_BUS_MODE_DATA structure.
+              If the bus width is changed (1 or 4 bit) the caller must adjust the mode flags
+          for the new width. Cards cannot be switched between 1/4 bit and SPI mode.
+          Switching to or from SPI mode requires a power cycle. Adjustments to the clock
+          rate is immediate on the next bus transaction.  The actual clock rate value is
+          limited by the host controller and is reported in the ClockRate field when the
+          command completes successfully.
+              The bus mode change is card wide and may affect other SDIO functions on
+          multi-function cards. Use this feature with caution. This feature should NOT be
+          used to dynamically control clock rates during runtime and should only be used
+          at card initialization. Changing the bus mode must be done with SDIO function
+          interrupts masked.
+              This request can block and must only be called from a schedulable context.
+
+  @example: Example of changing the clock rate:
+    SDCONFIG_BUS_MODE_DATA  busSettings;
+    ZERO_OBJECT(busSettings);
+       // get current bus flags and keep the same bus width
+    busSettings.BusModeFlags = SDDEVICE_GET_BUSMODE_FLAGS(pInstance->pDevice);
+    busSettings.ClockRate = 8000000;  // adjust clock to 8 Mhz
+       // issue config request to override clock rate
+    status = SDLIB_IssueConfig(pInstance->pDevice,

+  @notes: The message queue uses an internal list of user defined message structures.  The message is

+
+  @notes: This procedure can be called to issue an I/O abort request to an I/O function.
+          This procedure cannot be used to abort a data (block) transfer already in progress.
+          It is intended to be used when a data (block) transfer completes with an error and only if
+          the I/O function requires an abort action.  Some I/O functions may automatically
+          recover from such failures and not require this action. This function issues
+          the abort command synchronously and can potentially block.
+          If an async request is required, you must allocate a request and use
+          SDLIB_SetupIOAbortAsync() to prepare the request.
+
+  @example: Issuing I/O Abort synchronously :
+              .. check status from last block operation:
+              if (status == SDIO_STATUS_BUS_READ_TIMEOUT) {
+                   .. on failure, issue I/O abort
+                   status2 = SDLIB_IssueIOAbort(pDevice);
+              }
+            Issuing I/O Abort asynchronously:
+                ... allocate a request
+                ... setup the request:
+                 SDLIB_SetupIOAbortAsync(pDevice,pReq);
+                 pReq->pCompletion = myIOAbortCompletion;
