As an example, to set bit B9 of the questionable status enable register, set status.questionable.enable
= status.questionable.UO.
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 questionableRegister to the sum of their decimal weights.
For example, to set bits B12 and B13, set questionableRegister to 12,288 (which is the sum of 4,096 +
8,192).
