Measurement event register
The used bits of the Measurement Event Register (Figure 11-6) are described as follows:
•
Bit B0, Reading Overflow (ROF) — Set bit indicates that the reading exceeds the
measurement range of the instrument.
•
Bit B1, Low Limit 1 Event (LL1) — Set bit indicates that a reading has reached or
exceeded Low Limit 1.
•
Bit B2, High Limit 1 Event (HL1) — Set bit indicates that a reading has reached or
exceeded High Limit 1.
•
Bit B3, Low Limit 2 Event (LL2) — Set bit indicates that a reading has reached or
exceeded Low Limit 2.
•
Bit B4, High Limit 2 Event (HL2) — Set bit indicates that a reading has reached or
exceeded High Limit 2.
•
Bit B5, Reading Available (RAV) — Set bit indicates that a reading was taken and
processed.
NOTE
A programming example to read the RAV bit is provided in “Example 2 – Read
RAV bit of measurement event register” on page 11-20.
•
Bit B6, Buffer Notify (BN) — Set bit is a notification that the user-specified
number of readings have been stored in the buffer. The TRACe:NOTify command
specifies the number of stored readings that will set this bit (see Section 6 for
details).
•
Bit B7, Buffer Available (BAV) — Set bit indicates that there are at least two
readings in the buffer.
•
Bit B8, Buffer Half Full (BHF) — Set bit indicates that the trace buffer is half full.
NOTE
A programming example to read the BHF bit is provided in “Example 3 – Read
BHF bit of measurement event register” on page 11-20.
•
Bit B9, Buffer Full (BF) — Set bit indicates that the trace buffer is full.
•
Bit B10, Buffer Overflow (BOF) — Set bit indicates that the filled buffer has
wrapped and written over previously stored readings.
•
Bit B11, Hardware Limit Event (HL) — Set bit indicates that a reading has
exceeded the hardware limit.
•
Bit B12, Buffer Quarter Full (BQF) — Set bit indicates that the trace buffer is one-
quarter full.
NOTE
Bits B12 (¼ full) and B13 (¾ full) are not intended to be used with buffer sizes
smaller than four readings.
•
Bit B13, Buffer Three-Quarter Full (BTF) — Set bit indicates that the trace buffer
is three-quarters full.
