The LPC47M10x 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.
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.
Description
Each GPIO port has a 1-bit data register and an 8-bit configuration control register. The data register for each GPIO
port is represented as a bit in one of the 8-bit GPIO DATA Registers, GP1 to GP6. The bits in these registers reflect
the value of the associated GPIO pin as follows. Pin is an input: The bit is the value of the GPIO pin. Pin is an
output: The value written to the bit goes to the GPIO pin. Latched on read and write. All of the GPIO registers are
