4.7 Software Interrupt (SWI)
The SWI is an executable instruction and a non-maskable interrupt. It is
executed regardless of the state of the I bit in the CCR. If the I bit is 0
(interrupts enabled), SWI executes after interrupts which were pending
when the SWI was fetched but before interrupts generated after the SWI
was fetched. The interrupt service routine address is specified by the
contents of memory locations $1FFC and $1FFD.
