9.2.4 Interrupt Port Assignment Register (IRQPAR)
The interrupt port assignment register (IRQPAR), shown in Figure 9-5, provides the level
assignment of the primary external interrupt pins—IRQ5, IRQ3, and IRQ1. The setting of
IRQPAR2–IRQPAR0 determines the interrupt level of these external interrupt pins.
Table 9-8 describes IRQPAR fields.

Reserved, should be cleared.
Interrupt pending/mask. Each bit corresponds to an interrupt source defined by the ICR. The
corresponding IMR bit determines whether an interrupt condition can generate an interrupt. At
every clock, the IPR samples the signal generated by the interrupting source. The corresponding
IPR bit reflects the state of the interrupt signal even if the corresponding IMR bit is set.
0 The corresponding interrupt source is not masked (IMR) and has no interrupt pending (IPR).
1 The corresponding interrupt source is masked (IMR) and has an interrupt pending (IPR)
