Program Trace, Direct Branch
Program Trace, Direct Branch with Target Address
Program Trace, Indirect Branch
PTSY. In this case, the address of the instruction which generated the branch message can not
be explicitly reconstructed from the trace log, but the debugger will normally know which address
was returned to when Debug Mode was exited.
If a breakpoint occurs on the first instruction after exiting Debug Mode, a PTC message with
EVCODE = 0 is generated.
This message is output by the target processor whenever there is a change of program flow
caused by a conditional or unconditional branch. The instruction count (I-CNT) is included to
identify the branch address. The following AVR32 instructions can cause a direct branch:
Table 9-31.
Table 9-32.
This message is transmitted instead of the Direct Branch message when SQA enhanced pro-
gram trace is enabled by writing DC:SQA to one. This simplifies real-time PC reconstruction in
the emulator for real-time code coverage and performance analysis purposes.
Table 9-33.
An indirect branch is output by the target processor whenever there is a change of program flow
caused by a subroutine call, return instruction, interrupt, or exception.
