5.3.2. Undefined Instruction exception
The PTM upgrades the Undefined Instruction to a waypoint instruction
and outputs the following trace:
A waypoint
update packet, indicating the address of the Undefined Instruction
that the processor committed for execution.
An exception branch address packet that identifies
the Undefined Instruction exception and gives the address of the
exception vector.
An instruction might cause an Undefined Instruction exception
only if it passes its condition code check. If such an instruction
fails its condition code check, the PTM does not upgrade it to a
waypoint instruction.
