The NOTBUSY flag allows to deal with these different states.
0: The HSMCI is not ready for new data transfer. Cleared at the end of the card response.
1: The HSMCI is ready for new data transfer. Set when the busy state on the data line has ended. This corresponds to a
free internal data receive buffer of the card.
Refer to the MMC or SD Specification for more details concerning the busy behavior.
• SDIOIRQA: SDIO Interrupt for Slot A
0: No interrupt detected on SDIO Slot A.
1: An SDIO Interrupt on Slot A occurred. Cleared when reading the HSMCI_SR.
• SDIOIRQB: SDIO Interrupt for Slot B
0: No interrupt detected on SDIO Slot B.
1: An SDIO Interrupt on Slot B occurred. Cleared when reading the HSMCI_SR.
• SDIOWAIT: SDIO Read Wait Operation Status
0: Normal Bus operation.
1: The data bus has entered IO wait state.
• CSRCV: CE-ATA Completion Signal Received
