Usage
questionableRegister = status.questionable.unstable_output.condition
questionableRegister = status.questionable.unstable_output.enable
questionableRegister = status.questionable.unstable_output.event
questionableRegister = status.questionable.unstable_output.ntr
questionableRegister = status.questionable.unstable_output.ptr
status.questionable.unstable_output.enable = questionableRegister
status.questionable.unstable_output.ntr = questionableRegister
status.questionable.unstable_output.ptr = questionableRegister
operationRegister The status of the questionable status unstable output summary 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 questionable status unstable output summary registers. Reading
a status register returns a value. The binary equivalent of the returned value indicates which register bits are set.
The least significant bit of the binary number is bit B0, and the most significant bit is bit B15.
For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to
Status register set contents (on
page E-1) and Enable and transition registers (on page E-19). The individual bits of this register are defined in
the following table.
Bit Value Description
