command is used in SPI mode. Bits TY1 and
TY0 should be set to B'01 or B'10.
The transfer block size should be set in TBCR,
and the number of transfer blocks should be set
in TBNCR when a command to specify this bit
is used.

This bit is set to 1 when the CMD12M
command is specified. The CMD12M command
can be used only in MMC mode. Bits TY1 and
TY0 should be cleared to B'00.

should be set to B'01 or B'10. The stream
transfer can be used only in MMC mode.
The command sequence of the stream transfer
specified by this bit ends when it is aborted by
the CMD12M command.
