The output format has the form:

<qualifier> | <addr> <opcode> <assembly code>

The values below lists the possible qualifiers:

NE Not executed.
EX Executed.
AT Always taken. Conditional instruction which was always taken (condition always true).
NT Not Taken. Conditional instruction which was never taken (condition always false).
FT Fully Taken. Conditional instruction which was each taken and not taken for at least one time.

The output matches the display in the Disassembly window of the µVision debugger:
