If the software driver issues CMD13 to read the card bus when a CMD19 bus-test transaction is in progress on the bus, then the interface controller is affected by the CMD13 waiting for CRC status on the bus-test data.
This can be avoided by not sending a CMD13 when bus testing is in progress.
Systems that use the SDIO controller.
