The SDIO controller can send CMD13 during card programming mode to check the card status. If software sends an R1b response type command (e.g., CMD38, CMD6) followed by a CMD13 (status check), the controller sends the transfer complete before completing busy due to the CMD13 status check. This can be avoided by not sending a CMD13 immediately after sending an R1b command (e.g., CMD38, CMD6 etc.).
Minor, refer to the Work-around.
