CIRCC

Consumer Infrared Communications Controller

SMSC -> Microchip 

INTERFACE DESCRIPTION

The Interface Description lists the signals that

are required to place the CIrCC in a larger chip-

level context.

There are four groups of signals in this section:

PORT signals, HOST BUS controls, SYSTEM

controls, and CHIP-LEVEL CONFIGURATION

controls.

Ports

The three Ports (IR, COM, and AUX) provide

external access for serial data and controls. The

active CIrCC encoder is routed through the

Output Multiplexer to the IR, COM, or AUX port.
