Section 5 Interrupt Controller
Figure 5.3 shows the timing of the setting of the interrupt flags (IRQnF).
Interrupts IRQ
whether the corresponding pin is set for input or output. When using a pin for external interrupt
input, clear its DDR bit to 0 and do not use the pin for chip select output, refresh output, or SCI
input or output.
