Bank Active description added
… .In bank active mode, too, all banks become inactive after a
refresh cycle or after the bus is released as the result of bus
arbitration.
The bank active mode should not be used unless the bus width
for all areas is 32 bits.

This enables 32-, 64-, 128-, or 256-Mbit memory to be connected
to area 0 or area 2. However, only CS2/0 = 0 (area 0) should be
used for MCSCR0. Table 10.15 shows MCSCR0–MCSCR7

Description added
13. DMAC transfers should not be performed in the sleep mode
under conditions other than when the clock ratio of I
φ
(on-
chip clock) to B
φ
(bus clock) is 1:1.
14. When the following three conditions are all met, the
frequency control register (FRQCR) should not be changed
while a DMAC transfer is in progress.
while a DMAC transfer is in progress.
•
Bits IFC2 to IFC0 are changed.
•
STC2 to STC0 in FRQCR are not changed.
•
The clock ratio of I
φ
(on-chip clock) to B
φ
(bus clock) after
the change is other than 1:1.
