In addition to the above constants,
nodeEventRegister
can be set to the decimal equivalent of the
bits set. When more than one bit of the register is set,
nodeEventRegister
contains the sum of
their decimal weights. For example, if 129 is returned, bits B0 and B7 are set (1 + 128).

Example
nodeEventRegister = status.node_event
print(nodeEventRegister)
Reads the status node event register.
Sample output:
1.02
Converting this output (129) to its binary equivalent yields
1000 0001
. Therefore, this output indicates that the
set bits of the status byte condition register are presently B0 (MSB) and B7 (OSB).

These attributes manage the operation status register set of the status model.

Usage
operationRegister = status.operation.condition
operationRegister = status.operation.enable
operationRegister = status.operation.event
operationRegister = status.operation.ntr
operationRegister = status.operation.ptr
status.operation.enable = o perationRegister
status.operation.ntr = o perationRegister
status.operation.ptr = o perationRegister
operationRegister The status of the operation status register; a zero (0) indicates no bits set (also send
0 to clear all bits); other values indicate various bit settings
Details
These attributes read or write the operation status registers.
