IRQ timing specified at V
to T
Applies when IRQ pins are configured for rising edge or falling edge events, but not both.
eTPU timing specified at V
T
This specification does not include the rise and fall times. When calculating the minimum eTPU pulse width, include
the rise and fall times defined in the slew rate control fields (SRC) of the pad configuration registers (PCR).
