Bus
Width
Specify the bus width. Set to 11 for the MPX interface,
and set to 10 or 11 for the byte control SRAM interface.
In CS0BCR, the external pins (MODE3 and MODE4)
are sampled at a power-on reset.
00: Reserved
01: 8 bits
10: 16 bits
11: 32 bits
Note:
*
Bits SZ in CS0BCR are read-only. The SZ bits
in CS0BCR are set to 11 when area 0 is set to
the MPX interface by the MODE3 and MODE4
pins.
7 RDSPL
0 R/W
RD
Hold Cycle
Specifies the number of cycles to be inserted into the
RD
assertion period to elongate the data hold time for
the read data sample timing. When setting this bit to 1,
specify the number of
RD
negation-
CSn
negation delay
cycles as 1 or more by setting the RDH bit in CSnWCR.
Also the
RD
negation-
CSn
negation delay cycle is
reduced by 1 cycle when this bit is set to 1 (Available
only when the SRAM interface or byte control SRAM
interface).
0: No hold cycle inserted
1: 1 hold cycle inserted
6 to 4

R/W
Burst Pitch
When the burst ROM interface is used, these bits
specify the number of wait cycles to be inserted after
the second data access in a burst transfer.
000: No idle cycle inserted,

001: 1 idle cycle inserted,
