If the system designer uses the ITE IT8368E PC Card and multiple-function I/O buffer, the
S1D13704 can be interfaced so that it ’shares’ a PC Card slot. The S1D13704 is mapped to a rarely-
used 16M byte portion of the PC Card slot buffered by the IT8368E. This makes the S1D13704
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 S1D13704 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.
