Reserved, should be cleared.
Non-pipelined mode. Determines whether the core operates in pipelined or mode or not.
0 Pipelined mode
1 Nonpipelined mode. The processor effectively executes one instruction at a time with no overlap.
Regardless of the NPL state, a triggered PC breakpoint is always reported before the triggering
instruction executes. In normal pipeline operation, the occurrence of an address and/or data
breakpoint trigger is imprecise. In non-pipeline mode, triggers are always reported before the next
instruction begins execution and trigger reporting can be considered precise.

This adds at least 5 cycles to the execution time of each instruction. Given an average execution
latency of 1.6 cycles/instruction, throughput in non-pipeline mode would be 6.6 cycles/instruction,
approximately 25% or less of pipelined performance.
