GENERAL DESCRIPTION
This
Communications Controller (IrCC) function which
is common to a number of SMSC products
including the FDC37C669FR, FDC37C93xFR,
and FDC37C957FR devices. The IrCC consists
of two main architectural blocks: the ACE
16550A
UART
and
Communications Engine (SCE) (Figure 2). Each
block is supported by its own unique register set.

Synchronous
The IrCC UART-driven IrDA SIR and SHARP
ASK modes are backward-compatible with early
SMSC Super I/O and Ultra I/O infrared
implementations. The IrCC SCE supports IrDA
v1.1
.576Mbps,
1.152Mbps,
Consumer IR modes. All of the SCE modes use
DMA. The IrCC offers flexible signal routing and
programmable output control through the Raw
mode interface, General Purpose Data pins and
Output Multiplexer. Chip-level address decoding
is required to access the IrCC register sets.
