Section 7 DMA Controller
transfers. One 24-bit address and one 8-bit address are specified. The addresses are held fixed. The
transfer direction is determined automatically from the activation source.
Repeat Mode: One byte or word is transferred per request. A designated number of these transfers
are executed. When the designated number of transfers are completed, the initial address and
counter value are restored and operation continues. No CPU interrupt is requested. One 24-bit
address and one 8-bit address are specified. The transfer direction is determined automatically
from the activation source.
Normal Mode
Block Transfer Mode: One block of a specified size is transferred per request. A designated
number of block transfers are executed. At the end of each block transfer, one address is restored
to its initial value. When the designated number of blocks have been transferred, a CPU interrupt
can be requested. Both addresses are 24-bit addresses.

Auto-request
The DMAC is activated by register setup alone, and continues executing transfers until the
designated number of transfers have been completed. A CPU interrupt can be requested at
completion of the transfers. Both addresses are 24-bit addresses.
External request
One byte or word is transferred per request. A designated number of these transfers are
executed. A CPU interrupt can be requested at completion of the designated number of
transfers. Both addresses are 24-bit addresses.
Cycle-steal mode
The bus is released to another bus master after each byte or word is transferred.
Burst mode
Unless requested by a higher-priority bus master, the bus is not released until the
designated number of transfers have been completed.
