External Interrupt

External interrupts can be generated using GPIO pins.

XINT# Input X-BAR

Select the input X-BAR for external interrupt. In this case, # represents the number of the external interrupt. This parameter is available only for specific processors.

XINT# GPIO

Indicates the GPIO pins for triggering external interrupts. In this case, # represents the number of the external interrupt.

Note

  • For F2807x, F2837x, F28004x, F2838x, F280013x, F280015x, and F28P65x processors the XINT# GPIO is disabled.

  • This parameter is available only for specific processors.

XINT# Polarity

Select the polarity of the signal in GPIO pin. Rising edge, Falling edge or Falling and rising edge are the polarity signals. In this case, # represents the number of the external interrupt.
