19.6.1.2 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.

NOTE:

A software interrupt pushes PC onto the stack. A software interrupt does

not push PC – 1, as a hardware interrupt does.

19.6.1.3 Interrupt Status Registers

The flags in the interrupt status registers identify maskable interrupt

sources. Table 19-3 summarizes the interrupt sources and the interrupt

status register flags that they set. The interrupt status registers can be

useful for debugging.
