Comparison type (on)

Select an option from this drop-down list to specify the type of comparison that triggers the specified tracepoint:

Instr Exec

The tracepoint is set at the specified address when an instruction is executed at that address or in the address range.

Note: The address of every instruction presented to the execution unit is compared with the specified address. This includes any instructions that might not be executed due to their condition code evaluating to FALSE.

Instr Fetch

The tracepoint is set at the specified address when an instruction is fetched from memory at that address or in the address range.

Data Value Read

The tracepoint is set at the specified address when an  instruction access to that address reads data of the  value specified in equal to.   

Data Value Write

The tracepoint is set at the specified address when an  instruction access to that address writes data of the  value specified in equal to.   

Data Value Access

The tracepoint is set at the specified address when an  instruction access to that address reads or writes data of the  value specified in equal to.   

External Condition

The tracepoint is activated when the specified external condition is satisfied. It can be any of the following:

  • external inputs 1 to 4

  • EmbeddedICE watchpoints 1 to 4

  • access to ASIC memory maps 1 to 16

These correspond to single-bit output signals from the ETM. Refer to the RealView Debugger v1.8 Extensions User Guide and your ASIC documentation for details.
