NOTE:
SWI Instruction
A software interrupt pushes PC onto the stack. A software interrupt does
not push PC – 1, as a hardware interrupt does.
All reset sources always have higher priority than interrupts and cannot
be arbitrated.
The break module can stop normal program flow at a
software-programmable break point by asserting its break interrupt
output. See
break state by forcing it to the SWI vector location. Refer to the break
interrupt subsection of each module to see how each module is affected
by the break state.
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.
