Section 5 Interrupt Controller
Figure 5.4 shows the timing of IRQnF setting.
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. When the IRQ6 pin
is assigned as the IRQ6 interrupt input pin, then set the KMIMR6 bit to 0.
As interrupt request flags IRQ7F to IRQ0F are set when the setting condition is met, regardless of
the IER setting, only the necessary flags should be referenced.
