Example 2
-- 18432 = binary 0100 1000 0000 0000
operationRegister = 18432
status.operation.enable = operationRegister
Sets bits B11 and B14 of the operation
status user enable register using a
decimal value.
Also see
status.operation.* (on page 7-266)
Operation Status Register
(on page E-21)
status.questionable.*
These attributes manage the status model's questionable status register set.
Type TSP-Link accessible Affected by Where saved Default value
Attribute - - - - - - - -
.condition (R) Yes Not applicable Not saved Not applicable
.enable (RW) Yes Status reset Not saved 0

Usage
quesRegister = status.questionable.condition
quesRegister = status.questionable.enable
quesRegister = status.questionable.event
quesRegister = status.questionable.ntr
quesRegister = status.questionable.ptr
status.questionable.enable = quesRegister
status.questionable.ntr = quesRegister
status.questionable.ptr = quesRegister
quesRegister
The questionable status register's status. A zero (0) indicates no bits set (also send
0 to clear all bits); other values indicate various bit settings
Details
These attributes are used to read or write to the questionable status registers. Reading a status register returns a
value. In the binary equivalent, the least significant bit is bit B0, and the most significant bit is bit B15. For
example, if a value of 1.02400e+04 (which is 10,240) is read as the value of the condition register, the binary
equivalent is 0010 1000 0000 0000. This value indicates that bits B11 and B13 are set.
