Description
Block Direction
Block Enable
These bits specify whether normal mode or
block transfer mode is to be used for data
transfer. If block transfer mode is specified, the
BLKDIR bit specifies whether the source side
or the destination side is to be the block area.
×0: Transfer in normal mode
01: Transfer in block transfer mode
11: Transfer in block transfer mode (source
Reserved
These bits can be read from or written to.
However, the write value should always be 0.
