16.5.8.2. Read-Wait Sequence

Read_wait is used with SDIO cards only. It temporarily stalls the data transfer, either from functions or memory, and allows the host to send commands to any function within the SDIO card device. The host can stall this transfer for as long as required. The controller provides the facility to signal this stall transfer to the card.
