the CPU buffer before final-data storage stops altogether, resulting in a few
more records than advertised able to be collected. For example — on a
CR3000 storing a four-byte value at a 10-ms rate, the CPU not fill-and-stop,
CRD: set to fill-and-stop after 500 records — after final-data storage stopped,
CRD: had 603 records advertised in the Status table (an extra 103 due to the
extra 2 kB allocated for ring buffering), but 608 records could be collected
since it took 50 ms, or 5 records, to stop the CPU from storing its 5 records
beyond when the card was stopped.
8. Note that only the CRD: drive will keep storing until all its records are filled;
the CPU: drive will stop when the user specified number of records are stored.
9. Note that the O command in the terminal mode helps to visualize more
precisely what CPU: drive and the CRD: drive are doing, actual size allocated,
where they are at the present, etc.
