- 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

- The bus mode change is card wide and may affect other SDIO functions on

- 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

- @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
