Access Type:
• BCNT: MMC/SDIO Block Count - SDIO Byte Count
This field determines the number of data byte(s) or block(s) to transfer.
The transfer data type and the authorized values for BCNT field are determined by the TRTYP field in the MCI Command
Register (MCI_CMDR):
Warning: In SDIO Byte and Block modes, writing to the 7 last bits of BCNT field, is forbidden and may lead to unpredict-
able results.
• BLKLEN: Data Block Length
This field determines the size of the data block.
This field is also accessible in the MCI Mode Register (MCI_MR).
Bits 16 and 17 must be set to 0 if PDCFBYTE is disabled.
