Commands

TRACE Trace Into

Usage: TRACE <num>

The TRACE command allows single-instruction execution. If num is provided, then num

instructions are executed before control is handed back to dBUG. The value for num is a decimal

number.

The TRACE command sets bits in the processors’ supervisor registers to achieve single-instruction

execution, and the target code executed. Control returns to dBUG after a single-instruction

execution of the target code.

This command is repeatable.

Examples:

To trace one instruction at the program counter, the command is:

To trace 20 instructions from the program counter, the command is:

tr 20
