Example
questionableRegister =
status.questionable.instrument.smua.CAL +
status.questionable.instrument.smua.UO
status.questionable.instrument.smua.enable =
questionableRegister

questionableRegister
= status.questionable.over_temperature.condition
questionableRegister = status.questionable.over_temperature.enable
questionableRegister = status.questionable.over_temperature.event
questionableRegister = status.questionable.over_temperature.ntr
questionableRegister
= status.questionable.over_temperature.ptr
status.questionable.over_temperature.enable =
questionableRegister
status.questionable.over_temperature.ntr = questionableRegister
status.questionable.over_temperature.ptr = questionableRegister
operationRegister
