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).
