O: DACK output setting in dual address mode transfer
Notes: 1. SRAM-type in the table indicates an SRAM, byte control SRAM, or burst ROM.
(4) Bus Mode and Channel Priority Order
When, for example, channel 1 is transferring data in burst mode, and a transfer request is issued to
channel 0, which has a higher priority, the channel 0 transfer is started immediately.
If fixed mode has been set for the priority levels (CH0 > CH1), transfer on channel 1 is continued
after transfer on channel 0 is completely finished, whether cycle steal mode or burst mode is set
for channel 0.
If round robin mode has been set for the priority levels, transfer on channel 1 is restarted after one
transfer unit of data is transferred on channel 0, whether cycle steal mode or burst mode is set for
channel 0. Channel execution alternates in the order: channel 1 → channel 0 → channel 1 →
channel 0.
An example of round robin mode operation is shown in figure 11.12.
Since channel 1 is in burst mode (in the case of edge sensing) regardless of whether fixed mode or
round robin mode is set for the priority order, the bus is not released to the CPU until channel 1
transfer ends.
