The Ir CC 2.0 consists of two main architectural blocks: the ACE 16C550A UART and a Synchronous munications Engine (SCE) (Figure 2). It’s own unique register set supports each block. The Ir CC 2.0 UART-driven Ir DA SIR and SHARP ASK modes are backward patible with current SMSC Super I/O and Ultra I/O infrared implementations. The Ir CC 2.0 SCE supports Ir DA v1.1 0.576 Mbps, 1.152 Mbps, 4 Mbps, and Consumer IR modes. All of the SCEdriven modes can use DMA. The Ir CC 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 Ir CC 2.0 register sets. TABLE OF CONTENTS FEATURES 1 GENERAL DESCRIPTION...
