Description
Reserved
This bit can be read from or written to. However,
the write value should always be 0.
Destination Address Increment/Decrement
Destination Address Increment/Decrement
Enable
These bits specify whether destination address
register MARB is to be incremented,
decremented, or left unchanged, when data
transfer is performed.
00: MARB is fixed
01: MARB is incremented after a data transfer
10: MARB is fixed
11: MARB is decremented after a data transfer
Reserved
This bit can be read from or written to. However,
the write value should always be 0.
Data Transfer Factor 3 to 0
These bits select the data transfer factor
(activation source). The factors that can be
specified differ between normal mode and block
transfer mode.
When DTSZ = 0, MARB is incremented by 1
When DTSZ = 1, MARB is incremented by 2
When DTSZ = 0, MARB is decremented by
1
When DTSZ = 1, MARB is decremented by
2
