A block diagram of interrupts IRQ5 to IRQ0 is shown in figure 5-2.
Figure 5-3 shows the timing of setting IRQnF.
The vector numbers for IRQ5 to IRQ0 interrupt exception handling are 21 to 16.
Detection of IRQ5 to IRQ0 interrupts does not depend on whether the relevant pin has been set for
input or output. However, when a pin is used as an external interrupt input pin, do not clear the
corresponding DDR to 0 and use the pin as an I/O pin for another function.
