If the on chip debug system is enabled, this instruction traps a software breakpoint for debugging. The breakpoint instruc-
tion will enter debug mode disabling all interrupts and exceptions. If the on chip debug system is not enabled, this
instruction will execute as a nop.
If no on chip debug system is implemented, this instruction will execute as a "NOP".
