Program Trace, Direct Branch with Sync
Program Trace, Indirect Branch with Sync
Table 9-36.
If a Program Trace Synchronization message occurs on an instruction which transmits a direct
branch message, the Direct Branch with Sync message is transmitted instead of the Program
Trace Synchronization message. The Direct Branch with Sync message contains the instruction
count referring to the taken branch, as well as the complete PC value of the branch target.
The format for direct branch messages with sync is shown below. The AVR32 OCD system
never issues speculative branch messages and there is therefore no CANCEL packet.
Table 9-37.
If a Program Trace Synchronization message occurs on an instruction which transmits an indi-
rect branch message, the Indirect Branch with Sync message is transmitted instead of the
Program Trace Synchronization message. The Indirect Branch with Sync message contains the
instruction count referring to the taken branch, as well as the complete PC value of the branch
target.
