general-purpose input/output (GPIO)

To use the GP[7:4, 2] software-configurable GPIO pins, the GPxEN bits in the GP Enable (GPEN) Register and the GPxDIR bits in the GP Direction (GPDIR) Register must be properly configured.

GPxEN =	1	GP[x] pin is enabled
GPxDIR =	0	GP[x] pin is an input
GPxDIR =	1	GP[x] pin is an output

where “x” represents one of the 7 through 4, or 2 GPIO pins

Figure 9 shows the GPIO enable bits in the GPEN register for the device. To use any of the GPx pins as general-purpose input/output functions, the corresponding GPxEN bit must be set to “1” (enabled). Default values are device-specific, so refer to Figure 9 for the C6711D default configuration.

Figure 10 shows the GPIO direction bits in the GPDIR register. This register determines if a given GPIO pin is an input or an output providing the corresponding GPxEN bit is enabled (set to “1”) in the GPEN register. By default, all the GPIO pins are configured as input pins.
