Example
Sets the OTEMP bit of the questionable SMU A enable register:
status.questionable.instrument.smua.enable =
status.questionable.OTEMP
status.questionable.over_temperature.*
status.questionable.over_temperature.condition
status.questionable.over_temperature.enable
status.questionable.over_temperature.event
status.questionable.over_temperature.ntr
status.questionable.over_temperature.ptr
* = condition, enable, event, ntr or ptr
Attribute
Questionable over temperature event register set.
Usage
Reads condition, enable, event, NTR and PTR registers:
quesreg = status.questionable.over_temperature.condition
quesreg = status.questionable.over_temperature.enable
quesreg = status.questionable.over_temperature.event
quesreg = status.questionable.over_temperature.ntr
quesreg = status.questionable.over_temperature.ptr
Writes to enable, NTR and PTR registers:
status.questionable.over_temperature.enable = quesreg
status.questionable.over_temperature.ntr = quesreg
status.questionable.over_temperature.ptr = quesreg
Set
operreg
to one of the following values:
0
Clears all bits.
status.questionable.over_temperature.SMUA
Sets SMUA bit (B1).
status.questionable.over_temperature.SMUB
Sets SMUB (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
• This attribute is used to read or write to the questionable over temperature 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 instrument registers are described as follows:
•
Bit B1, SMUA
– Set bit indicates the enabled OTEMP bit for the SMU A
questionable register is set.
•
Bit B2, SMUB
– Set bit indicates the enabled OTEMP bit for the SMU B
questionable register is set.
