•
Write 1 to the CMDOFF bit when a CRC error (CRCERI) or command timeout error (CTERI)
occurs in the command response reception.
•
Clear the FIFO by writing 1 to the CMDOFF bit when a CRC error (CRCERI) or data timeout
error (DTERI) occurs in the read data reception.
Note: In multiblock transfer, when the command sequence is ended (write 1 to the CMDOFF
bit) before command response reception (CRPI), the command response may not be
received correctly. Therefore, to receive the command response, the command sequence
must be continued (set the RD_CONTI bit to 1) until the command response reception
ends.
