6.2 Pin description
6.2.1 General description
The LPC2917/19 has up to four ports: two of 32 pins each, one of 28 pins and one of 16
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.
