General description
The LPC2939 uses five ports: port 0 and port 1 with 32 pins, ports 2 with 28 pins each,
port 3 with 16 pins, port 4 with 24 pins, and port 5 with 20 pins. The pin to which each
function is assigned is controlled by the SFSP registers in the SCU. The functions
combined on each port pin are shown in the pin description tables in this section.
