Instructions
NOOP The NOOP instruction means there is no instruction for this line.
BREak The BREak instruction causes the execution of the sequence to
stop at this line. Use the RESume command to advance to the next
sequence line.
SIGNal The SIGNal instruction is the complement of the WAIT IMB
instruction. When the pattern generator encounters a SIGNal
instruction, it will output a signal to the internal Intermodule Bus (IMB).
This signal is used to trigger the logic analyzer.
WAIT The Wait instruction causes the pattern generator to stop and
wait for the occurrence of the specified event pattern(s). The event
patterns are specified elsewhere (SEQuence: EPATtern command). The
event to be waited for by this particular command is specified by the
optional instruction argument parameter. Once the specified event
occurs, the pattern generator program proceeds to the next state.
Valid wait events are { A | B | C | D | IMB }
IF The IF instruction allows a sequence of program states to occur if a
specified condition is true. The IF event pattern can be specified
elsewhere (SEQuence:EPATtern command).
The condition to be tested by the IF instruction is specified by the optional
instruction argument parameter. If the specified condition is true, the
sequence states included in the IF (lines between IF and IF END) are
executed. If the condition is not true, the sequence states within the IF are
skipped. Valid IF events are {IF | IMB}.
Note that there are clock speed, channel count, and location restrictions on
the use of the IF instruction.
REPeat The REPeat instruction allows a group of sequence states to be
executed repetitively some number of times. The repeat count is
specified in the optional instruction argument parameter.
Inserting a REPeat instruction causes three sequence lines to be generated.
The REPeat instruction line, a data line within the body of the repeat, and an
END LOOP instruction line.
No data appears in the REPEAT and END LOOP lines. The data specified as
part of the remote control command string appears in the body of the repeat
loop. Additional data lines can be added to the body of the repeat loop by
