17.2.7. Software interrupts

The software can control the source interrupt lines to generate software interrupts. These interrupts are generated before interrupt masking, in the same way as external source interrupts. Software interrupts are cleared by writing to the software interrupt clear register, VICSoftIntClear (see Interrupt control registers). This is normally done at the end of the interrupt service routine.
