status.questionable.instrument.condition

status.questionable.instrument.event
status.questionable.instrument.ntr
status.questionable.instrument.ptr
Attribute Questionable status instrument summary register set.
Default 0
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage Reads condition, enable, event, NTR, and PTR registers:
quesreg = status.questionable.instrument.condition
quesreg = status.questionable.instrument.enable
quesreg = status.questionable.instrument.event
quesreg = status.questionable.instrument.ntr
quesreg = status.questionable.instrument.ptr
Writes to enable, NTR, and PTR registers:
status.questionable.instrument.enable = quesreg
status.questionable.instrument.ntr = quesreg
status.questionable.instrument.ptr = quesreg
Set operreg to one of the following values:
0 Clears all bits.
status.questionable.instrument.SMUA Sets SMUA bit (B1).
status.questionable.instrument.SMUB Sets SMUB bit (B2).
quesreg can also be set to the decimal weight of the bit to be set. Examples:
To set bit B1 (SMUA), set quesreg to 2 (2
1
).
To set bit B2 (SMUB), set quesreg to 4 (2
2
).
To set both bits, set quesreg to the sum of the decimal weights of both bits.
To set bits B1 and B2, set quesreg to 6 (2 + 4).
Remarks • These attributes are used to read or write to the questionable status instrument summary
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 6 is returned for the enable register. The binary equivalent is
0000000000000110. This value indicates that bit B1 (SMUA) and bit B2 (SMUB) are set.
• The used bits of the questionable status instrument summary registers are described as follows:
• Bit B1, SMUA: Set bit indicates one or more enabled bits for the SMU A questionable register is
set.
• Bit B2, SMUB: Set bit indicates one or more enabled bits for the SMU B questionable register is
set.
Details See Questionable Status Register in Appendix C.
Example Sets the SMUA bit of the questionable status instrument summary enable register:
status.questionable.instrument.enable =
status.questionable.instrument.SMUA
