NOTE:
Address:
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.

These flags indicate the presence of interrupt requests from the
sources shown in
1 = Interrupt request present
0 = No interrupt request present
