INTRODUCTION
The IrCC Consumer IR (TV Remote) block is a
general-purpose programmable Amplitude Shift
Keyed serial communications interface that
includes
Programmable Receive Carrier Range Sensitivity
Register, and Receive and Transmit Modulators
(Figure 4).
The Consumer IR block transfers data between
the SCE and Output Multiplexer without framing
as a fixed bit-cell serial NRZ data stream. The
components of this block can also modulate and

demodulate serial data at programmable bit rates
and carrier frequencies.
Variable length encoding and all packet framing
is handled by system software. Consequently,
many encoding methods, modulation frequencies
and bit rates can be supported, including 38KHz
PPM, PWM and RC-5 TV Remote formats.
Register controls for this block can be found in
Register Block Two. They are the Consumer IR
Control Register, the Consumer IR Carrier Rate
Register, and the Consumer IR Bit Rate
Register.
