DMA Control Register Bit Settings
Notes:
1. DMAR must be inactive at the end of cycle 9 to guarantee three transfers.
2. Peripheral data bus width must match DRAM bus width.
3. See diagram for settings.
4. This waveform assumes that the internal address mux is used.
5. CAS0 is used for byte accesses, CAS0:1 for halfwords, and CAS0:3 for fullwords.
6. Numbers (
1
,
2
,
3
,...) in the DMAR signal represent when DMAR is sampled and accepted. Numbers (
1
,
2
,
3
,...) in the
DMAA signal represent the transfers associated with the accepted DMAR.
