general-purpose input/output (GPIO)  
To use the GP[15:0] 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.

GP[x] pin is enabled  
GP[x] pin is an input  
GP[x] pin is an output  
where “x” represents one of the 15 through 0 GPIO pins  
Figure 7 shows the GPIO enable bits in the GPEN register for the C6414T/C6415T/C6416T 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 7 for the C6414T/15T/16T default configuration.

Figure 7. GPIO Enable Register (GPEN) [Hex Address: 01B0 0000]  
Figure 8 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.
