General Mobile Application Processor
The transceiver is directly
interfaced with the
microprocessor provided its
support infrared communication
commonly known as Infrared
Communications Port (ICP). The
ICP supports both SIR data rates
up to 115.2 kps and sometimes
FIR data with data rates up to

4 Mbps. The remote control
commands can be sent to one of
the available General Purpose IO
pins or the UART block with IrDA
functionality. It should be
observed that although both IrDA
data transmission and Remote
control transmission is possible
simultaneously by the hardware,
the software is required to resolve
this issue to prevent the mixing
and corruption of data while
being transmitted over the free
air. The above Figure 3 illustrates
a reference interfacing to
implement both IR and RC
functionality with HSDL-3021.
