This field determines the size of the data block.
This field is also accessible in the MR register.
If MR.FBYTE bit is zero, the BLKEN[17:16] field must be written to 0b00
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 CMDR.TRTYP field:
Warning: In SDIO Byte and Block modes, writing to the seven last bits of BCNT field is forbidden and may lead to unpredictable
results.
