8.6 Launching the recorder
The recorder is launched (or killed) using the RR command. RR also reports the recorder
status.
The RR command has the following options:
RR Value Meaning
-1 Kill the recorder if active, and invalidate any recorded data.
0 Kill the recorder (Do nothing if the recorder is not active)
1 Launch the recorder, triggered on the next BG.
2 Launch the recorder with immediate trigger.
3 Launch the recorder with the trigger defined by the RP parameters.
Table 8-4: RR command options
Note that the actions of RR=1 and RR=2 can be obtained with RR=3 and the appropriate
RP[N] definitions. The commands RR=1 and RR=2 are simply meant to allow easy interface
to the most common recorder actions.
As a status report, RR may return the following values:
RR Report Meaning
-1 No valid data in the recorder.
0 The recorder action is complete, and it is loaded with valid data.
1,2,3 Waiting for the completion of RR=1, RR=2, or RR=3 respectively.
The report value of 1,2, and 3 does not tell if the recorder is already
recording or is just waiting for a trigger. If this differentiation is
required, use the SR
command.
Table 8-5: RR reports
The SR (Status Register) command details the status of the recorder. SR returns a bit field.
Bits 16 and 17 of SR may have the following values:
Bit 16 Bit 17 Recorder status
0 0 Recorder inactive, no valid recorded data
0 1 Recorder armed, waiting for a trigger event
1 0 Recorder finished; valid data is ready for use.
1 1 Recording now.
