5.2 Input/Output Pins
Table 5.1 summarizes the pins of the interrupt controller.
Table 5.1 Pin Configuration
Pin Name I/O Function
NMI Input
Nonmaskable external interrupt pin
Rising edge or falling edge can be selected
IRQ15 to IRQ0,
ExIRQ15 to ExIRQ6
Input
Maskable external interrupt pins
Rising-edge, falling-edge, or both-edge detection, or level-
sensing, can be selected individually for each pin. To which
pin the IRQ15 to IRQ6 interrupt is input can be selected from
the IRQm and ExIRQm pins. (n = 15 to 6)
KIN15 to KIN0 Input Maskable external interrupt pins
When EIVS = 0, falling-edge or level-sensing can be
selected.
When EIVS = 1, an interrupt is requested at the falling edge.
WUE15 to WUE8 Input Maskable external interrupt pins
Either rising edge or falling edge detection can be selected
for each pin.
