TMS320C6452 General Purpose Input/Output (GPIO) User's Guide
Describes the general-purpose input/output (GPIO) peripheral in the TMS320C6452 Digital Signal Processor (DSP). The GPIO peripheral provides dedicated general-purpose pins that can be configured as either inputs or outputs. When configured as an input, you can detect the state of the input by reading the state of an internal register. When configured as an output, you can write to an internal register to control the state driven on the output pin.
