1 Introduction

This manual describes the interface between the S1D13704/5 LCD Controller (LCDC) and the TMPR3912/22U microprocessor as implemented on the Toshiba 3912/22 and S1D13704/5 CPU Module. This module is used in conjunction with the Toshiba TX RISC Reference Platform.

For more information regarding the S1D13704 or S1D13705 refer to their respective

Hardware Functional Specification, document number X26A-A-001-xx and

X27A-A-001-xx respectively.

For more information regarding the TMPR3912/22U, refer to the TMPR3912/22U 32-Bit MIPS RISC Processor User’s Manual. See the Toshiba website under semiconductors at http://toshiba.com/taec/nonflash/indexproducts.html.

1.1 General Description

The Toshiba TX RISC Reference Kit consists of 6 boards which include: a main board, a CPU board, a EPROM board, a FMEM board, a debug board, and an analog board. The main board acts as the motherboard for all the other add-on boards. In addition to these boards, there is an LCD module that connects to the CPU board. In order to support the add-on LCD panel that connects to the LCD module, the CPU board microprocessor must have an internal LCD controller or the CPU board must have an LCD controller on it that interfaces to the microprocessor.

For the TMPR3912/22U microprocessor, the S1D13704 or S1D13705 LCDC is used to provide support for LCD panels. The LCDC is socketed so that it can be interchanged between the S1D13704 and the S1D13705. These controllers are very similar, with the main differences being the amount of embedded display memory and the lookup-table architecture (LUT). The S1D13704 has 40K bytes of display memory and the S1D13705 has 80K bytes.

The Toshiba TMPR3912/22U processor supports two PC Card (PCMCIA) slots on the TX RISC Reference Platform. The S1D13704 or S1D13705 LCD controller uses the PC Card slot 1 to interface to the TMPR3912/22U, therefore, this slot is unavailable for use on the TX RISC Reference Platform.
