1 = The Receive Counter Register has reached 0 since the last write in MCI_RCR or MCI_RNCR.
• ENDTX: End of TX Buffer
0 = The Transmit Counter Register has not reached 0 since the last write in MCI_TCR or MCI_TNCR.
1 = The Transmit Counter Register has reached 0 since the last write in MCI_TCR or MCI_TNCR.
Note: BLKE and NOTBUSY flags can be used to check that the data has been successfully transmitted on the data lines and not only
transferred from the PDC to the MCI Controller.
• 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.
Note: BLKE and NOTBUSY flags can be used to check that the data has been successfully transmitted on the data lines and not only
transferred from the PDC to the MCI Controller.
• RINDE: Response Index Error
0 = No error.
1 = A mismatch is detected between the command index sent and the response index received. Cleared when writing in
the MCI_CMDR.
• RDIRE: Response Direction Error
0 = No error.
1 = The direction bit from card to host in the response has not been detected.
• RCRCE: Response CRC Error
0 = No error.
1 = A CRC7 error has been detected in the response. Cleared when writing in the MCI_CMDR.
• RENDE: Response End Bit Error
0 = No error.
1 = The end bit of the response has not been detected. Cleared when writing in the MCI_CMDR.
• RTOE: Response Time-out Error
0 = No error.
1 = The response time-out set by MAXLAT in the MCI_CMDR has been exceeded. Cleared when writing in the
MCI_CMDR.
• 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.
