Details
These attributes are used to read or write to the questionable status over temperature 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 B0, and the most significant bit is bit B15.
For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to
page E-1) and
the following table.
Bit
B0
B1
B2
B3-B15
As an example, to set bit B1 of the questionable status over temperature summary enable register, set
status.questionable.instrument.enable = status.questionable.instrument.SMUA.
In addition to the above constants, questionableRegister can be set to the numeric equivalent of the bit to
set. To set more than one bit of the register, set operationRegister to the sum of their decimal weights. For
example, to set bits B1 and B2, set questionableRegister to 6 (which is the sum of 2 + 4).
Example
status.questionable.over_temperature.enable =
status.questionable.over_temperature.SMUA

Description
Not applicable.
Set bit indicates that an over temperature
condition was detected on SMU A.
