The S1D13705 requires an addressing space of 128K bytes. The on-chip display memory occupies
the range 0 through 13FFFh. The registers occupy the range 1FFE0h through 1FFFFh. The
PR31500/PR31700 demultiplexed address lines A17 and above are ignored, thus the S1D13705 is
aliased 512 times at 128K byte intervals over the 64M byte PC Card slot #1 memory space. In this
example implementation, the PR31500/PR31700 control signal /CARDREG is ignored; therefore
the S1D13705 also takes up the entire PC Card slot 1 configuration space.
Note: If aliasing is undesirable, additional decoding circuitry must be added.
The S1D13705 is configured at power up by latching the state of the CNF[3:0] pins. Pin BS# also
plays a role in host bus interface configuration. For details on configuration, refer to the “S1D13705
Hardware Functional Specification”, document number X27A-A-001-02.
The table below shows those configuration settings relevant to the direct connection approach.
If the system designer uses the ITE IT8368E PC Card and multiple-function I/O buffer, the
S1D13705 can be interfaced so that it “shares” a PC Card slot. The S1D13705 is mapped to a rarely-
used 16M byte portion of the PC Card slot buffered by the IT8368E. This makes the S1D13705
virtually transparent to PC Card devices that use the same slot.
The ITE8368E has been specially designed to support EPSON LCD controllers. The ITE IT8368E
provides eleven Multi-Function IO pins (MFIO). Configuration registers may be used to allow these
MFIO pins to provide the control signals required to implement the S1D13705 CPU interface.
The PR31500/PR31700 processor only provides addresses A[12:0]; therefore devices requiring
more address space must use an external device to latch A[25:13]. The IT8368E’s MFIO pins can be
configured to provide this latched address.
