Example
operationRegister =
status.operation.trigger_overrun.SMUA +
status.operation.trigger_overrun.TRGBLND
status.operation.trigger_overrun.enable = operationRegister
Uses constants to set bit
B1 and bit B10 of the
operation status trigger
overrun summary enable
register.
Also see
Operation Status Registers (on page E-9)
status.operation.* (on page 7-270)
status.operation.user.*
These attributes manage the operation status user register set of the status model.
Type TSP-Link accessible Affected by Where saved Default value
Attribute - - - - - - - -
.condition (RW) Yes Status reset Not saved 0
.enable (RW) Yes Status reset Not saved 0
.event (R) Yes Status reset Not saved 0
.ntr (RW) Yes Status reset Not saved 0
.ptr (RW) Yes Status reset Not saved 32,767 (All bits set)
Usage
operationRegister = status.operation.user.condition
operationRegister = status.operation.user.enable
operationRegister = status.operation.user.event
operationRegister = status.operation.user.ntr
operationRegister = status.operation.user.ptr
status.operation.user.condition = operationRegister
status.operation.user.enable = operationRegister
status.operation.user.ntr = operationRegister
status.operation.user.ptr = operationRegister
operationRegister The status of the operation status user register; 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 operation status user registers. Reading a status register returns
a value. The binary equivalent of the value indicates which register bits are set. 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
1.02
(which is
129) is read as the value of the condition register, the binary equivalent is 0000 0000 1000 0001. This value
indicates that bits B0 and B7 are set.
