*PRE (Parallel Poll Enable Register Enable)
Command *PRE <mask>
The *PRE command sets the Parallel Poll Register enable bits. The Parallel
Poll Enable Register contains a mask value that is ANDed with the bits in the
Status Bit Register to enable an "ist" during a parallel poll. Refer to table 8-4
for the bits in the Parallel Poll Enable Register and for what they mask.
<pre_mask> An integer from 0 to 65535.
Example This example will allow the Agilent 1670G-series logic analyzer to generate
an "ist" when a message is available in the output queue. When a message is
available, the MAV (Message Available) bit in the Status Byte Register will be
high.
Output XXX;"*PRE 16 "
