Example
operationRegister =
status.operation.trigger_overrun.SMUA +
status.operation.trigger_overrun.TRGBLND
status.operation.trigger_overrun.enable = operationRegister
Sets bit B1 and bit B10 of
the operation status
trigger overrun summary
enable register using
constants.

These attributes manage the status model's operation status user register 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 operation status user 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 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 1.29000e+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.
