17.1 Introduction
17.2 IrDA Interfaces
This module implements the physical layer of an infrared serial port that is compliant with
Version 1.1 of the Infrared Data Association (IrDA) standard. It supports communication
speeds of up to 4 MBit/s. When combined with analog transducer components, it provides a
complete interface between infrared media and an AMBA compliant peripheral bus (APB).
Three different encoder/decoder units implement the supported modulation schemes and
data encoding systems defined by the IrDA standard:
The Infrared Interface Module implements in hardware the physical layer of an infrared serial
port, compliant with version 1.1 of the IrDA standard. Communication speeds of up to
4 Mbit/sec are supported. When combined with analog transducer components, it provides a
complete interface between infrared media and an AMBA compliant peripheral bus (APB).
The Module comprises three separate encoder/decoder units for implementing three different
combinations of modulation scheme and data encoding system defined by the IrDA standard.
These are:
• Slow Infrared (SIR) - This interface attaches to the output of UART2. The UART2
• Medium Infrared (MIR) - Transmission/reception rates can be 0.576 or 1.152 Mb/s.
• Fast Infrared (FIR) - Transmission/reception rate is 4 Mb/s.
• Slow Infrared - SIR - This interface attaches to the output of a UART. All data and control
• Medium Infrared - MIR - This interface is independent of a UART.
• Fast Infrared - FIR - This interface is independent of a UART. Transmission/reception
registers handle the data and control for this interface, though the IrDA interface enable
register selects the SIR function.
for this interface is done through the UART registers. The SIR encoder function is
selected using the IrDA interface enable register.
Transmission/reception rates can be 0.576 or 1.152 Mbit/sec.
rates can be 4 Mbit/sec.
