Description
Data Transfer Size
Selects the size of data to be transferred at one
time.
0: Byte-size transfer
1: Word-size transfer
Source Address Increment/Decrement
Source Address Increment/Decrement Enable
These bits specify whether source address
register MARA is to be incremented,
decremented, or left unchanged, when data
transfer is performed.
00: MARA is fixed
01: MARA is incremented after a data transfer
•
•
10: MARA is fixed
11: MARA is decremented after a data transfer
•
•
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.
x0: Transfer in normal mode
01: Transfer in block transfer mode (destination
11: Transfer in block transfer mode (source side is
When DTSZ = 0, MARA is incremented by 1
When DTSZ = 1, MARA is incremented by 2
When DTSZ = 0, MARA is decremented by 1
When DTSZ = 1, MARA is decremented by 2
