Input X-BAR

The crossbars (X-bars) provides flexibility to connect device inputs, outputs, and internal resources in a variety of configurations using Input X-BAR, Output X-BAR, and ePWM X-BAR.

The Input X-BAR is used to route signals from a GPIO to many different peripherals blocks such as the ADC(s), eCAP(s), ePWM(s), and external interrupts. The Input X-BAR has access to every GPIO and can route each signal to any (or multiple) of the peripherals blocks.

INPUT# pin assignment

Specify a valid GPIO number from which the signal will be passed to the corresponding destinations. When pin assignment is None, the corresponding Input X-Bar will not be configured.
