Reset
237
In standby, sleep, and manual reset, control registers of the
bus state controller are not initialized. At manual reset, the
current bus cycle being executed is completed and then the
access wait state is entered.
Since the RTCNT continues
counting up during manual reset signal assertion, a refresh
request occurs to initiate the refresh cycle.
Note that arbitration requests using
BREQ
are not accepted
during manual reset signal assertion.

The priority of round-robin mode is CH0 > CH1 > CH2 >
CH3 immediately after a reset.
When the round-robin mode is specified, cycle-steal mode
and burst mode should not be mixed among the bus modes
for multiple channels.
