1. If the command is SEND_OP_COND, the CRC error flag is always present (refer to R3 response in the MultiMedia Card
Data Transfer Operation
Read Operation
specification).
Check error bits in the
The MultiMedia Card allows several read/write operations (single block, multiple blocks, stream,
etc.). These kind of transfers can be selected setting the Transfer Type (TRTYP) field in the MCI
Command Register (MCI_CMDR).
These operations can be done using the features of the Peripheral DMA Controller (PDC). If the
PDCMODE bit is set in MCI_MR, then all reads and writes use the PDC facilities.
In all cases, the block length (BLKLEN field) must be defined in the mode register MCI_MR. This
field determines the size of the data block.
The following flowchart shows how to read a single block with or without use of PDC facilities. In
this example (see
