Debug data control. Controls operand data capture for DDATA, which displays the number
of bytes defined by the operand reference size before the actual data; byte displays 8 bits,
word displays 16 bits, and long displays 32 bits (one nibble at a time across multiple
PSTCLK cycles). See

User halt enable. Selects the CPU privilege level required to execute the HALT instruction.
0 HALT is a supervisor-only instruction.
1 HALT is a supervisor/user instruction.
Branch target bytes. Defines the number of bytes of branch target address DDATA

1 Nonpipelined mode. The processor effectively executes one instruction at a time with
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.
Ignore pending interrupts.
1 Core ignores any pending interrupt requests signalled while in single-instruction-step
mode.
0 Core services any pending interrupt requests that were signalled while in single-step

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.
