5 Using the ITE IT8368E PC Card Buffer

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.

5.1 Hardware Description

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.
