-+
-+ @notes:
-+ The bus driver maintains an internal queue of SDREQUEST structures submited by function
-+ drivers. The driver should use request macros to obtain a pointer to the current SDREQUEST
-+ at the head of the queue. The driver can access the fields of the current request in order
-+ to program hardware appropriately. Once the request completes, the driver should update
-+ the current request information (final status, response bytes and/or data) and call
-+ SDIO_HandleHcdEvent() with the event type of EVENT_HCD_TRANSFER_DONE.
-+ The bus driver will remove the current request from the head of the queue and start the next
-+ request.
-+
-+ @example: Example of a typical Request callback:
-+ SDIO_STATUS HcdRequest(PSDHCD pHcd)

-+ If the bus width is changed (1 or 4 bit) the caller must adjust the mode flags

-+ 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

-+ @return: SDIO_STATUS
-+
-+ @notes: Host controller drivers must call into this function to validate various command
-+ responses before continuing with data transfers or for decoding received SPI tokens.
-+ The CheckMode option determines the type of validation to perform.
-+ if (CheckMode == SDHCD_CHECK_DATA_TRANS_OK) :
-+ The host controller must check the card response to determine whether it
-+ is safe to perform a data transfer. This API only checks commands that
-+ involve data transfers and checks various status fields in the command response.
-+ If the card cannot accept data, this function will return a non-successful status that
-+ should be treated as a request failure. The host driver should complete the request with the
-+ returned status. Host controller should only call this function in preparation for a
-+ data transfer.
-+ if (CheckMode == SDHCD_CHECK_SPI_TOKEN) :
-+ This API checks the SPI token and returns a timeout status if the illegal command bit is
-+ set. This simulates the behavior of SD 1/4 bit operation where illegal commands result in
-+ a command timeout. A driver that supports SPI mode should pass every response to this
-+ function to determine the appropriate error status to complete the request with. If the
-+ API returns success, the response indicates that the card accepted the command.
-+
-+ @example: Checking the response before starting the data transfer :
-+ if (SDIO_SUCCESS(status) && (pReq->Flags & SDREQ_FLAGS_DATA_TRANS)) {
-+ // check the response to see if we should continue with data
-+ status = SDIO_CheckResponse(pHcd, pReq, SDHCD_CHECK_DATA_TRANS_OK);
-+ if (SDIO_SUCCESS(status)) {
-+ .... start data transfer phase
-+ } else {
-+ ... card response indicates that the card cannot handle data
-+ // set completion status
-+ pRequest->Status = status;
-+ }

-+ was supporting has been removed. The device has already been removed, so no further I/O
-+ to the device can be performed.
-+
-+ @example: Example of typical Remove function callback:

-+ PSDXXX_DRIVER_CONTEXT pFunctionContext =
-+ (PSDXXX_DRIVER_CONTEXT)pFunction->pContext;

-+ can block on semaphores and sleep.

-+ 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);
