measurementRegister
The status of the measurement event current limit summary register; a zero (0)
indicates no bits set (also send 0 to clear all bits); the only valid value other
than 0 is 2
Details
These attributes are used to read or write to the measurement event current 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 example,
assume the value 2 is returned for the enable register. The binary equivalent is 0000 0000 0000 0010. This value
indicates that bit B1 (SMUA) is set.
For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to
(on
Enable and transition registers
(on page E-19). The individual bits of this register are defined in
the following table.
Bit Value
Description
B0
Not used
Not applicable.
B1
status.measurement.current_limit.SMUA
Set bit indicates that the current 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 current limit summary enable register, set
status.measurement.current_limit.enable = status.measurement.current_limit.SMUA
.
In addition to the above constant,
measurementRegister
can be set to the decimal equivalent of the bit to set.
