questionableRegister
Details
These attributes are used to read or write to the questionable status calibration 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
2) and Enable and transition registers
meanings:
Bit Value
B0 Not used
B1
status.questionable.calibration.SMUA
B2-B15 Not used
In addition to the above constant, questionableRegister can be set to the decimal equivalent of the bit to
set.
Example
status.questionable.calibration.enable =
status.questionable.calibration.SMUA
