When an interrupt is generated, it is registered as a pending interrupt. The interrupt will remain pending until its interrupt enable
bit is set (Figure 19-1 and Figure 19-2) and interrupts are globally enabled (Bit 2, Processor Status and Control Register). At
that point the internal interrupt handling sequence will clear the IRQ Pending bit until another interrupt is detected as pending.
This bit is only valid if the Global Interrupt Enable bit is disabled.
