7. DMA Controller
IOAR specifies the lower 8 bits of a fixed address. The upper 16 bits are all 1s. IOAR is not
incremented or decremented.
Figure 7.2 illustrates how I/O mode operates.
The transfer count is specified as a 16-bit value in ETCR. The ETCR value is decremented by 1 at
each transfer. When the ETCR value reaches H'0000, the DTE bit is cleared and the transfer ends.
If the DTIE bit is set to 1, a CPU interrupt is requested at this time. The maximum transfer count
is 65,536, obtained by setting ETCR to H'0000.
