Example 1
operationRegister = status.operation.user.BIT11 +
status.operation.user.BIT14
status.operation.user.enable = operationRegister
Uses constants to set bits B11 and B14
of the operation status user enable
register.
Example 2
-- 18432 = binary 0100 1000 0000 0000
operationRegister = 18432
status.operation.enable = operationRegister
Uses a decimal value to set bits B11 and
B14 of the operation status user enable
register.
Also see
Operation Status Register (on page E-9)
status.operation.*
(on page 7-265)
status.questionable.*
These attributes manage the status model's questionable status register set.

Usage
questionableRegister = status.questionable.condition
questionableRegister = status.questionable.enable
questionableRegister = status.questionable.event
questionableRegister = status.questionable.ntr
questionableRegister = status.questionable.ptr
status.questionable.enable = questionableRegister
status.questionable.ntr = questionableRegister
status.questionable.ptr = questionableRegister
questionableRegister
The status of the questionable status register; a zero (0) indicates no bits set
(also send 0 to clear all bits); other values indicate various bit settings
