Section 11 Local Bus State Controller (LBSC)
Rev. 1.00 Oct. 01, 2007 Page 364 of 1956
REJ09B0256-0100
While the PCMCIA interface is used, the
CE1A
/
CS5
and
CE2A
signals, the
RD
signal, (which
can be used as
OE
), the
WE0
,
WE1
,
WE2
, and
WE3
signals, (which can be used as,
PCC_REG
,
WE
,
IORD
, and
IOWR
, respectively) are asserted.
As regards the number of bus cycles, 0 to 25 wait cycles inserted by CS5WCR can be selected.
Any number of wait cycles can be inserted in each bus cycle through the external wait pin (
RDY
).
(When the insert number is 0, the
RDY
signal is ignored.)
The setup time and hold time (cycle number) of the address and
CS5
signals to the read and write
strobe signals can be set within a range of 0 to 7 cycles by CS5WCR. The
BS
hold cycles can be
set within a range of 0 to 1 when the number of read and write strobe setup wait is 1 or more.
For the PCMCIA interface, the setup time of addresses to the read/write strobe signals (
CE1A
/
CS5
and
CE2A
) can be specified within a range from 0 to 15 cycles through bits TEDA[2:0],
TEDB[2:0], TEHA[2:0], and TEHB[2:0] in CS5PCR. In addition, the number of wait cycles can
be specified within a range from 0 to 50 cycles through bits PCWA[1:0] and PCWB[1:0] The
number of wait cycles specified by CS5PCR is added to the value specified by IW[3:0] in
CS5WCR or PCIW[3:0] in CS5PCR.
When the DDR-SDRAM is used, see section 12, DDR-SDRAM Interface (DDRIF).
(7)
Area 6
For area 6, external address bits A28 to A26 are 110.
The interfaces that can be set for this area are the SRAM, MPX, burst ROM, and PCMCIA
interfaces.
When the SRAM or burst ROM is used, a bus width of 8, 16, or 32 bits is selectable with bits
SZ[1:0] in CS6BCR. When the MPX interface is used, a bus width of 32 bits should be selected
through bits SZ[1:0] in CS6BCR. When the PCMCIA interface is used, select a bus width of 8 or
16 bits with SZ[1:0] in CS6BCR. For details, see section 11.3.2, Memory Bus Width.
While the SRAM interface is used, the
CS6
signal is asserted when area 6 is accessed. In addition,
the
RD
signal, which can be used as
OE
, and write control signals
WE0
to
WE3
are asserted.
While the PCMCIA interface is used, the
CE1B
/
CS6
and
CE2B
signals, the
RD
signal (which can
be used as
OE
), and the
WE0
,
WE1
,
WE2
, and
WE3
signals (which can be used as
PCC_REG
,
WE
,
IORD
, and
IOWR
, respectively) are asserted.
As regards the number of bus cycles, 0 to 25 wait cycles inserted by CS6WCR can be selected.
