This field determines the size of the data block.
This field is also accessible in the BLKR register.
If FBYTE bit is zero, the BLKEN[1:0] field must be written to 0b00
0: 0x00 value is used when padding data in write transfer.
1: 0xFF value is used when padding data in write transfer.
PADV is used only in manual transfer.
Enabling Force Byte Transfer allows byte transfers, so that transfer of blocks with a size different from modulo 4 can be
supported.
Warning: BLKLEN value depends on FBYTE.
Writing a one to this bit will enable the Force Byte Transfer.
Writing a zero to this bit will disable the Force Byte Transfer.
Enabling Write Proof allows to stop the MCI Clock (CLK) during write access if the internal FIFO is full. This will guarantee data
integrity, not bandwidth.
Writing a one to this bit will enable the Write Proof mode.
Writing a zero to this bit will disable the Write Proof mode.
Enabling Read Proof allows to stop the MCI Clock (CLK) during read access if the internal FIFO is full. This will guarantee data
integrity, not bandwidth.
Writing a one to this bit will enable the Read Proof mode.
Writing a zero to this bit will disable the Read Proof mode.
