The peripheral signals are multiplexed with general-purpose input/output (GPIO) signals. On reset, GPIO pins are configured as inputs. For specific inputs, the user can also select the number of input qualification cycles to filter unwanted noise glitches.
Many GPIOs have mux options for Output X-BAR which allows an assortment of internal signals to be routed to a GPIO. All of the GPIOs are connected to each Input X-BAR which can route the GPIO's high or low state to different IP blocks, such as the ADCs, eCAPs, ePWMs, and external interrupts. For more details, see the X-BAR chapter in the TMS320F28P55x Real-Time Microcontrollers Technical Reference Manual.
