You download the datasheet from the manufacturer. Count the number of available port pins on the processor and the number of signals required for the I/O. If

Processor_Port_Pins <= I/O signals

Then you hook them up in any convenient fashion.
So what's the problem?

you may need around 8-Bits of data and for that 1-Port is enough. Though 8051 has 4 Ports (32 bits), the data may be serial and for that you need only Rx,Tx (2 Pins).

This issue is very interesting. I will begin to study this topic.
