Error information is messaged out in the following format:

Data Trace Synchronization Messages
A data trace write/read w/ sync. message is messaged via the auxiliary port (provided data trace is enabled)
for the following conditions (refer to
•
Initial data trace message upon exit from system reset or whenever data trace is enabled will be a
synchronization message.
•
Upon returning from a low power state, the first data trace message will be a synchronization
message.
•
Upon returning from debug mode, the first data trace message will be a synchronization message.
•
After occurrence of queue overrun (can be caused by any trace message), the first data trace
message will be a synchronization message.
•
After the periodic data trace counter has expired indicating 255
without-sync
data trace messages
have occurred since the last
with-sync
message occurred.
•
Upon assertion of the Event In (EVTI) pin, the first data trace message will be a synchronization
message if the eic bits of the dc register have enabled this feature.
•
Upon data trace write/read after the previous dtm message was lost due to an attempted access to
a secure memory location.
•
Upon data trace write/read after the previous dtm message was lost due to a collision entering the
fifo between the dtm message and any of the following: error message, or watchpoint message.
Data trace synchronization messages provide the full address (without leading zeros) and insure that
development tools fully synchronize with data trace regularly. Synchronization messages provide a
reference address for subsequent DTMs, in which only the unique portion of the data trace address is
transmitted. The format for data trace write/read w/ sync. messages is as follows:
