Idle mode
⎯ 1-byte or 1-word transfer executed
⎯ Memory address fixed
⎯ 1 to 65,536 transfers
Repeat mode
⎯ 1-byte or 1-word transfer executed
⎯ Memory address incremented/
⎯ After specified number of transfers
Single address mode
1-byte or 1-word transfer executed for
one transfer request
Transfer in 1 bus cycle using DACK pin
in place of address specifying I/O
Specifiable for sequential, idle, and
repeat modes
for one transfer request
incremented/decremented by 1 or 2
for one transfer request
for one transfer request
decremented by 1 or 2
(1 to 256), initial state is restored
and operation continues
