AT91SAM9R64/RL64 Preliminary
• DCRCE: Data CRC Error
0 = No error.
1 = A CRC16 error has been detected in the last data block. Reset by reading in the MCI_SR register.
• DTOE: Data Time-out Error
0 = No error.
1 = The data time-out set by DTOCYC and DTOMUL in MCI_DTOR has been exceeded. Reset by reading in the MCI_SR
register.
• OVRE: Overrun
0 = No error.
1 = At least one 8-bit received data has been lost (not read). Cleared when sending a new data transfer command.
• UNRE: Underrun
0 = No error.
1 = At least one 8-bit data has been sent without valid information (not written). Cleared when sending a new data transfer
command.
• SDIOIRQA: SDIO Interrupt for Slot A
0 = No interrupt detected on SDIO Slot A.
1 = A SDIO Interrupt on Slot A has reached. Cleared when reading the MCI_SR.
• SDIOIRQB: SDIO Interrupt for Slot B
0 = No interrupt detected on SDIO Slot B.
1 = A SDIO Interrupt on Slot B has reached. Cleared when reading the MCI_SR.
• RXBUFF: RX Buffer Full
0 = MCI_RCR or MCI_RNCR has a value other than 0.
1 = Both MCI_RCR and MCI_RNCR have a value of 0.
• TXBUFE: TX Buffer Empty
0 = MCI_TCR or MCI_TNCR has a value other than 0.
1 = Both MCI_TCR and MCI_TNCR have a value of 0.
