5.1 Hardware Description
S1D13705
X27A-G-004-02
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, making the
S1D13705 virtually transparent to PC Card devices that use the same slot.
The ITE8368E has been specially designed to support EPSON LCD controllers and
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 TMPR3912 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.
