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
•
•
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
