13.6.1.2 SWI Instruction
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.
13.6.2 Interrupt Status Registers
The flags in the interrupt status registers identify maskable interrupt sources.
interrupt sources and the interrupt status register flags that they set. The interrupt status registers can be
useful for debugging.
