Example
status.questionable.unstable_output.enable =
status.questionable.unstable_output.SMUA
Uses a constant to set the SMU A bit in the questionable status unstable output summary enable register bit.

status.questionable.*
status.request_enable
This attribute stores the service request (SRQ) enable register.
Type TSP-Link accessible
Attribute (RW) Yes
Usage
requestSRQEnableRegister = status.request_enable
status.request_enable = requestSRQEnableRegister
requestSRQEnableRegister
Details
This attribute is used to read or write to the service request enable register. Reading the service
request enable register returns a value. The binary equivalent of the value of this attribute indicates
which register bits are set. In the binary equivalent, the least significant bit is bit B0, and the most
significant bit is bit B7. For example, if a value of 1.29000e+02 (which is 129) is read as the value of
this register, the binary equivalent is 1000 0001. This value indicates that bit B0 and bit B7 are set.
