Figure 5.3 shows the timing of setting IRQnF.
The vector numbers for IRQ7 to IRQ0 interrupt exception handling are 23 to 16.
Detection of IRQ7 to IRQ0 interrupts does not depend on whether the relevant pin has been set for
input or output. Therefore, when a pin is used as an external interrupt input pin, do not clear the
corresponding DDR bit to 0 and use the pin as an I/O pin for another function. The pins that can
be used for IRQ4 to IRQ7 interrupt input can be switched by means of the IRQPAS bit in SYSCR.
