RCA, which must be used in order to select the card in the future
for data transfers. The card will then move into standby mode,
completing the identification procedure.

Single Block Write Operations

Block write operations typically consist of 512 bytes of data per block.
If the card is found to support other block lengths or the default block
length as specified in the CID register is not 512, the block length of the
RSI must be configured accordingly. The block length of the card and the
block length of the RSI must be configured for the same block size at all
times. The block length of the RSI is configured via the
field of the
RSI_DATA_CONTROL

It is important to pay attention as to when the data path state
machine is enabled and when data is written to the FIFO for trans-
fer to the card. Write transactions require that data be written after
the response has completed for the

this procedure can result in data being written to the card in viola-
tion to the block write timing parameters, resulting in a data CRC
failure.
