30.3
Real-time trace, which defines the dynamic execution path, is a fundamental debug function. The ColdFire
solution is to include a parallel output port providing encoded processor status and data to an external
development system. This port is partitioned into two 4-bit nibbles: one nibble allows the processor to
transmit processor status, (PST), and the other allows operand data to be displayed (debug data, DDATA).
The processor status may not be related to the current bus transfer.
External development systems can use PST outputs with an external image of the program to completely
track the dynamic execution path. This tracking is complicated by any change in flow, especially when

two consecutive rising CLKOUT edges.) Clocks the serial communication port to the debug

Internally synchronized input that provides data input for the serial communication port to the

Provides serial output communication for debug module responses. DSO is registered internally.
Input used to request a manual breakpoint. Assertion of BKPT puts the processor into a halted
state after the current instruction completes. Halt status is reflected on processor status signals

DDATA values.
These output signals display the register breakpoint status as a default, or optionally, captured
address and operand values. The capturing of data values is controlled by the setting of the CSR.
Additionally, execution of the WDDATA instruction by the processor captures operands which are
displayed on DDATA. These signals are updated each processor cycle.
These output signals report the processor status.

not related to the current bus transfer. The PST value is updated each processor cycle.
