As an example, to set bit B1 of the operation status trigger overrun summary enable register, set
status.operation.trigger_overrun.enable = status.operation.trigger_overrun.SMUA.
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 B1 and B10, set operationRegister to 1026 (which is the sum of 2 + 1024).
