IRQ5 to IRQ0 Interrupts: Interrupts IRQ5 to IRQ0 are requested by an input signal at pins IRQ5
to IRQ0. Interrupts IRQ5 to IRQ0 have the following features:
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.

Using ISCR, it is possible to select whether an interrupt is generated by a low level, falling
edge, rising edge, or both edges, at pins IRQ5 to IRQ0.
Enabling or disabling of interrupt requests IRQ5 to IRQ0 can be selected with IER.
The interrupt priority level can be set with IPR.
The status of interrupt requests IRQ5 to IRQ0 is indicated in ISR. ISR flags can be cleared to 0
by software.
