WebThese flags are usually stored as bits within an interrupt register. The processor can read from and write to the interrupt register, reading from it to find out which interrupts occurred and writing to it to clear the interrupt flags. Interrupt mask The interrupt mask has a set of bits identical to those in the interrupt register. WebAs shown in Figure 2.1 (p. 4) each IRQ line can be triggered by one or more interrupt flags (IF). Normally these interrupt flags will be set by a hardware condition (e.g. timer overflow), but SW can also set and clear these directly by writing to the IFS (Interrupt Flag Set register) or IFC (Interrupt Flag Clear register).
