Trigger Capture Mode
Value Constant Description
0
API429_MON_CAP_STANDARD
Standard Capture Mode
The ‘Trace After Trigger Count tat’ defines
the number of entries to be stored in the
Monitor Buffer after
the occurence of the
Trigger Start Event.
1
API429_MON_CAP_RECORDING
Recording Mode
The receiver monitor is setup in Continuous
Capture Mode. The ‘Trace After Trigger
Count tat’ is implicitly set to zero in order to
enable Continuous Capturing (Recording),
‘rec_filesize’ is used to define the amount of
Receiver Monitor Data for a long-time
recording session. In Recording Mode the
Buffer Full/Half Buffer Full Interrupt is
enabled. So every time, the API429
Receiver Monitor has captured a certain
amount of data, an interrupt is asserted.
