The LPC2926/2927/2929 uses five ports: port 0 with 32 pins, ports 1 and 2 with 28 pins
each, port 3 with 16 pins, and port 5 with 2 pins. Port 4 is not used. The pin to which each
function is assigned is controlled by the SFSP registers in the System Control Unit (SCU).
The functions combined on each port pin are shown in the pin description tables in this
section.
