2.1.7. 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. You clear software interrupts by writing to the Software Interrupt Clear Register, VICSoftIntClear. See Software Interrupt Clear Register. This is normally done at the end of the interrupt service routine.
