(A) National Semiconductor Super

I/O and Infrared Controller

For National Semiconductor

Super I/O and Infrared Controller

chips, IR link can be realized with

the following connections:

• Connect IRTX of the National

Super I/O or IR Controller to

TXD (pin 9) of the HSDL-3602.

• Connect IRRX1 of the National

Super I/O or IR Controller to

RXD (pin 8) of the HSDL-3602.

• Connect IRSL0 of the National

Super I/O or IR Controller to

FIR_SEL (pin 3) of the HSDL-

3602.

Please refer to the table below for

the IR pin assignments for the

National Super I/O and IR Con-

trollers that support IrDA 1.1 up

to 4 Mb/s:
