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
Section 11. Break
by forcing it to the SWI vector location. Refer to the break interrupt
Freescale Semiconductor, Inc.
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.
