Development support involves complex interactions between
MC68HC912DT128A resources and external development systems.
The following section concerns instruction queue and queue tracking
signals, background debug mode, and instruction tagging.
The CPU12 instruction queue provides at least three bytes of program
information to the CPU when instruction execution begins. The CPU12
always completely finishes executing an instruction before beginning to
execute the next instruction. Status signals IPIPE[1:0] provide
information about data movement in the queue and indicate when the
CPU begins to execute instructions. This makes it possible to monitor
CPU activity on a cycle-by-cycle basis for debugging. Information
available on the IPIPE[1:0] pins is time multiplexed. External circuitry
can latch data movement information on rising edges of the E-clock
signal; execution start information can be latched on falling edges.
