Comments
·
In BLOCk(ing) mode, if the FIFO becomes full and measurements are still being
made, the new values are discarded.
·
OVERwrite mode is used to record the latest 65,024 values. The module must be
halted (ABORT sent) before attempting to read the FIFO. In OVERwrite Mode, if
the FIFO becomes full and measurements are still being made, new values
overwrite the oldest values.
·
In both modes Error 3021, “FIFO Overflow” is generated to indicate that
measurements have been lost.
