Description
This document describes the Infrared Communications Controller (IrCC 2.0) function, which is common to a number of Microchip products. The IrCC 2.0 consists of two main architectural blocks: the ACE 16C550A UART and a Synchronous Communications Engine (SCE. It?s own unique register set supports each block. The IrCC 2.0 UART-driven IrDA SIR and SHARP ASK modes are backward compatible with current Microchip Super I/O and Ultra I/O infrared implementations. The IrCC 2.0 SCE supports IrDA v1.1 0.576 Mbps, 1.152 Mbps, 4 Mbps, and Consumer IR modes. All of the SCE-driven modes can use DMA. The IrCC 2.0 offers flexible signal routing and programmable output control through the Raw mode interface, General Purpose Data pins and Output Multiplexer. Chiplevel address decoding is required to access the IrCC 2.0 register sets.
