Remarks
These attributes are used to read or write to the questionable status registers.
Reading a status register returns a value. The binary equivalent of the returned value
indicates which register bits are set. The least significant bit of the binary number is bit
0, and the most significant bit is bit 15.
For example, assume value 4352 is returned for the enable register. The binary
equivalent is 0001000100000000. This value indicates that bit B8 (CAL) and bit B12
(S4THR, Slot 4 thermal bit) are set.
The used bits of the questionable event registers are described as follows:
Bit B1, S1INL - Set bit indicates that the interlock connection of a card in
Slot 1 is in question.
Bit B2, S2INL - Set bit indicates that the interlock connection of a card in
Slot 2 is in question.
Bit B3, S3INL - Set bit indicates that the interlock connection of a card in
Slot 3 is in question.
Bit B4, S4INL - Set bit indicates that the interlock connection of a card in
Slot 4 is in question.
Bit B5, S5INL - Set bit indicates that the interlock connection of a card in
Slot 5 is in question.
Bit B6, S6INL - Set bit indicates that the interlock connection of a card in
Slot 6 is in question.
Bit B7, DMMCON - Set bit indicates that the DMM connection is in question
for a measurement taken.
Bit B8, CAL - Set bit indicates that the calibration of the instrument is in
question
Bit B9, S1THR - Set bit indicates that the thermal aspect of a card in Slot 1
is in question.
Bit B10, S2THR - Set bit indicates that the thermal aspect of a card in Slot
2 is in question.
Bit B11, S3THR - Set bit indicates that the thermal aspect of a card in Slot
3 is in question.
Bit B12, S4THR - Set bit indicates that the thermal aspect of a card in Slot
4 is in question.
Bit B13, S5THR - Set bit indicates that the thermal aspect of a card in Slot
5 is in question.
Bit B14, S6THR- Set bit indicates that the thermal aspect of a card in Slot
6 is in question.
