26.7
When the little endian is specified, the access size for registers or that for memory where the
corresponding data is stored should be fixed. For example, if data read from the MMCIF with the
word size is written to memory and then it is read from memory with the byte size, data mis-
alignment occurs.

26.8.1
(1) Summary
The MMCIF may not receive the command response correctly, when it finishes receiving the end
bit of the first data block before receiving the end bit of the command response. It may occur after
MMCIF issued CMD18 to the receive device.
(2) Conditions under which the phenomenon occurs
This phenomenon occurs when all of the following operations occur.
1. The multiblock read command (CMD18) is issued.
2. The transfer data block size is setting to 1, 2, 4, or 8 byte(s).
3. The end bit of the command response is received after the end bit of the data block is received.
(3) Workaround
1. The transfer data block size in Transfer Byte Number Count Register (TBCR) must be more
2. Confirm that the end bit of the command response is received before the end bit of the first

than 16 bytes when CMD18 is issued.
data block is received, if the transfer data block size is 1, 2, 4, or 8 bytes when CMD18 is
transmitted.
Keep the below formula in order to confirm that the end bit of the command response is
received before the end bit of the first data block is received.
