status.questionable.over_temperature.*
This attribute contains the questionable status over temperature summary register set.
Type TSP-Link accessible Affected by Where saved Default value
Attribute - - - - - - - -
.condition (R) Yes Not applicable Not saved Not applicable

Usage
questionableRegister = status.questionable.over_temperature.condition
questionableRegister = status.questionable.over_temperature.enable
questionableRegister = status.questionable.over_temperature.event
questionableRegister = status.questionable.over_temperature.ntr
questionableRegister = status.questionable.over_temperature.ptr
status.questionable.over_temperature.enable = questionableRegister
status.questionable.over_temperature.ntr = questionableRegister
status.questionable.over_temperature.ptr = questionableRegister
operationRegister
The questionable status over temperature summary register's status. A zero (0)
indicates no bits set (also send 0 to clear all bits); the only valid value other than
zero (0) is 2
Details
These attributes are used to read or write to the questionable status over temperature 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 sets
(on page E-
2) and Enable and transition registers
(on page E-18). The individual bits of this register have the following
meanings:
Bit Value Description
B0 Not used Not applicable.
B1
status.questionable.over_temperature.SMUA
Set bit indicates that an over temperature
indication was detected.
Bit B1 decimal value: 2
Binary value: 0000 0010
B2-B15 Not used Not applicable.
In addition to the above constants, questionableRegister can be set to the numeric equivalent of the bit to
set.
Example
status.questionable.over_temperature.enable =
status.questionable.over_temperature.SMUA
Sets the SMU A bit in the
questionable status over
temperature summary enable
register using a constant.
