General Mobile Application Processor
Figure 3: HSDL-3021 configuration with general mobile architecture processor.
The transceiver is directly interfaced with the micropro-
cessor 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 re-
mote control commands can be sent to one of the avail-
able 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.
