eMIOS timing specified at f
50 pF with SRC = 0b00
There is no limitation on the peripheral for setting the minimum pulse width, the actual width is restricted by the pad delays.
Refer to the pad specification section for the details.
Parameter values guaranteed by design.
Parameter values guaranteed by design.
Applies when IRQ/NMI pins are configured for rising edge or falling edge events, but not both.
