12.1 How to read this chapter
The number of GPIO pins available on each port depends on the LPC111x/LPC11Cxx part
and the package. See Table 172
for available GPIO pins:
Register bits corresponding to PIOn_m pins which are not available are reserved.
12.2 Introduction
12.2.1 Features
• GPIO pins can be configured as input or output by software.
• Each individual port pin can serve as an edge or level-sensitive interrupt request.
• Interrupts can be configured on single falling or rising edges and on both edges.
• Level-sensitive interrupt pins can be HIGH or LOW-active.
