In addition to the above constants, measurementRegister can be set to the decimal equivalent of
the bit to set. To set more than one bit of the register, set measurementRegister to the sum of
their decimal weights. For example, to set bits B1 and B8, set measurementRegister to 258
(which is the sum of 2 + 256).

Example
status.measurement.enable = status.measurement.BAV
Sets the BAV bit of the measurement
event enable register.

Usage
nodeEnableRegister = status.node_enable
status.node_enable = nodeEnableRegister
nodeEnableRegister
The status of the system node enable register; a zero (0) indicates no bits set (also
send 0 to clear all bits); other values indicate various bit settings
Details
This attribute is used to read or write to the system node enable register. Reading the system node
enable register returns a value. The binary equivalent of the value of this attribute indicates which
register bits are set. In the binary equivalent, the least significant bit is bit B0, and the most significant
bit is bit B7. For example, if a value of 1.29000e+02 (which is 129) is read as the value of this
register, the binary equivalent is 1000 0001. This value indicates that bit B0 and bit B7 are set.
