6.14 GENERAL PURPOSE I/O
The LPC47M14x provides a set of flexible Input/Output control functions to the system designer through the 37
dedicated independently programmable General Purpose I/O pins (GPIO). The GPIO pins can perform basic I/O and
many of them can be individually enabled to generate an SMI and a PME.
6.14.1 GPIO Pins
The following pins include GPIO functionality. These pins are defined in the table below. All GPIOs default to the
GPIO function except for GP34 and GP35 which default to IRRX2 and IRTX2.
