Using the GPIO Pins
You can use the User Port Direction and User Port Value system parameters to address the GPIO pins to set
the user port direction (input or output) and the user port value (high or low). For more information, see
the following:
“User Port Direction”
in section 13.3.9
“User Port Value”
in section 13.3.10
NOTE
–
GPIO3 is used as a data ready pin when in SPI or I
2
C mode. GPIO3 cannot be used as GPIO when using
these interfaces.
