The F28044 device supports three masked external interrupts (XINT1, XINT2, XNMI). XNMI can be connected to the INT13 or NMI interrupt of the CPU. Each of the interrupts can be selected for negative, positive, or both negative and positive edge triggering and can also be enabled/disabled (including the XNMI). The masked interrupts also contain a 16-bit free running up counter, which is reset to zero when a valid interrupt edge is detected. This counter can be used to accurately time stamp the interrupt. Unlike the 281x devices, there are no dedicated pins for the external interrupts. Rather, any Port A GPIO pin can be configured to trigger any external interrupt.
