|
||
+ 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
