There is an additional feature disc for DMA interrupt request by DMA
END. Each channel has the following additional specific capabilities:
Channel 0

Channel 1

DMAC Registers
Each channel of the DMAC (channel 0, 1) contains three registers
specifically associated with that channel.
DREQ Input
Level- and edge-sense DREQ input detection are selectable.
TEND Output Used to indicate DMA completion to external devices.
Transfer Rate
Each byte transfer occurs every 6 clock cycles. Wait States can be
inserted in DMA cycles for slow memory or I/O devices. At the
system clock (f) = 6 MHz, the DMA transfer rate is as high as 1.0
megabytes/second (no Wait States).
Memory to memory
Memory to I/O
Memory to memory mapped I/O transfers.
Memory address increment, decrement, no-change
Burst or cycle steal memory to/from memory transfers
DMA to/from both ASCI channels
Higher priority than DMAC channel 1
Memory to/from I/O transfer
Memory address increment, decrement
