Bit 13—Source Address Increment/Decrement Enable (SAIDE): These bits specify whether
source address register MARA is to be incremented, decremented, or left unchanged, when data
transfer is performed.
Bit 12—Block Direction (BLKDIR)
Bit 11—Block Enable (BLKE): These bits specify whether normal mode or block transfer mode
is to be used. If block transfer mode is specified, the BLKDIR bit specifies whether the source side
or the destination side is to be the block area.
For operation in normal mode and block transfer mode, see section 7.5, Operation.
Bits 10 to 7—Reserved: Can be read or written to.
Bit 6—Destination Address Increment/Decrement (DAID)
