Details
These attributes are used to read or write to the measurement event voltage limit 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.measurement.voltage_limit.SMUA
Set bit indicates that the voltage limit was
exceeded.
Bit B1 decimal value: 2
Binary value: 0000 0010
B2-B15 Not used Not applicable.
As an example, to set bit B1 of the measurement event voltage limit summary enable register, set
status.measurement.voltage_limit.enable = status.measurement.voltage_limit.SMUA.
In addition to the above constant, measurementRegister can be set to the numeric equivalent of the bit to set.
Example
status.measurement.voltage_limit.enable =
status.measurement.voltage_limit.SMUA
Sets the SMUA bit of the
measurement event voltage limit
summary enable register using a
constant.

Measurement Event Registers (on page E-23)
status.node_enable
This attribute stores the system node enable register.
Type TSP-Link accessible Affected by Where saved Default value
Attribute (RW) Yes Status reset Not saved 0
Usage
nodeEnableRegister = status.node_enable
status.node_enable = nodeEnableRegister
nodeEnableRegister
The system node enable register's status. A zero (0) indicates no bits set (also send
0 to clear all bits); other values indicate various bit settings
