 """Reads and returns a number of instructions captured by STRACE. The number of instructions must be a non-negative value of at most ``0x10000`` (``65536``). Args: self (JLink):
 the ``JLink`` instance. num_instructions (int):
 number of instructions to fetch. Returns: A list of instruction addresses in order from most recently executed to oldest executed instructions. Note that the number of instructions returned can be less than the number of instructions requested in the case that there are not ``num_instructions`` in the trace buffer. Raises: JLinkException: on error. ValueError: if ``num_instructions < 0`` or ``num_instructions > 0x10000``. """
