5.2.1
Non-maskable Software Interrupt (SWI)
The software interrupt (SWI) is an executable instruction and a non-maskable interrupt: it is
execute regardless of the state of the I-bit in the CCR. If the I-bit is zero (interrupt enabled), SWI
is executed after interrupts that were pending when the SWI was fetched, but before interrupts
generated after the SWI was fetched. The SWI interrupt service routine address is specified by
the contents of memory locations $1FFC and $1FFD.
