supervisor portions), advances the program counter to point to the next instruction, and
stops the fetching and executing of instructions. A trace, interrupt, or reset exception
causes the processor to resume instruction execution. A trace exception occurs if
instruction tracing is enabled (T0 = 1, T1 = 0) when the STOP instruction begins
execution. If an interrupt request is asserted with a priority higher than the priority level
set by the new status register value, an interrupt exception occurs; otherwise, the
interrupt request is ignored. External reset always initiates reset exception processing.
