1 Introduction

The TIR2000 is a serial communication controller with full infrared support which is also compatible to the

TL16C550C and the TL16C750 UART devices. This device also supports the Sharp-IR, HPSIR, MIR, FIR

and TV modes. The controller has a 64-byte FIFO which reduces the CPU of excessive software overhead.

Also a 64-byte FIFO meets the minimum frame size requirements simplifying the software driver design.

DMA and interrupt support for all operations have been included in this architecture. The TIR2000 offers

programmable registers for routing interrupt DMA handshake signals. While in UART mode, the 64-byte

FIFO and selectable auto-flow control for RTS and CTS increases system efficiency and baud rate.
