1 Introduction
This application note describes the hardware and software environment required to provide an
interface between the SED1374 Embedded Memory Color Graphics LCD Controller and the
Toshiba MIPS TX3912 Processor.
For further information on the SED1374, refer to the SED1374 Hardware Functional Specification,
document number X26A-A-001-xx.
For further information on the TX3912, contact Toshiba or refer to the Toshiba website under

For further information on the ITE IT8368E, refer to the IT8368E PC Card / GPIO Buffer Chip
Specification.
1.1 General Description
The Toshiba MIPS TX3912 processor supports up to two PC Card (PCMCIA) slots. It is through
this host bus interface that the SED1374 connects to the TX3912 processor.
The SED1374 can be successfully interfaced using one of two configurations:
• Direct connection to TX3912 (see Section 2, “Direct Connection to the Toshiba TX3912” on
page 8).
• System design using one ITE IT8368E PC Card/GPIO buffer chip (see Section 3, “System
Design Using the ITE IT8368E PC Card Buffer” on page 10).
