R: Applications set this to 1 if BURST is non-zero
BURST: burst type
- 0: x1
- 1: x4
- 2: x8
- 3: ?
TYPE: data type
- 0: 8 bit
- 1: 16 bit
- 2: 32 bit
- 3: ?
W: Transfer direction
- 0: read from external memory
- 1: write to external memory
E: Applications always set this.
D0..D7: Connects to DMA channel 0..7 if set to one
