The LPC2921/2923/2925 uses three ports: port 1 with 32 pins, port 1 with 28 pins, and
port 5 with 2 pins. Ports 4/3/2 are not used. 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.
