Rev. 1.1
The SWI instruction is a non-maskable instruction that causes an
interrupt regardless of the state of the interrupt mask (I bit) in the
condition code register.
A software interrupt pushes PC onto the stack. A software interrupt does
not push PC – 1, as a hardware interrupt does.
The flags in the interrupt status registers identify maskable interrupt
sources.
status register flags that they set. The interrupt status registers can be
useful for debugging.
