As an example, to set bit B0 of the operation status user enable register, set
status.operation.user.enable = status.operation.user.BIT0.
In addition to the above constants, operationRegister 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 B11 and B14, set operationRegister to 18,432 (which is the sum of 2048 + 16,384).
