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.operation.instrument.SMUA
Set bit indicates one or more
enabled bits for the operation
status SMU A summary register is
set.
Bit B1 decimal value: 2
B2-B9 Not used Not applicable.
B10
status.operation.instrument.TRIGGER_BLENDER
status.operation.instrument.TRGBLND
Set bit indicates one or more
enabled bits for the operation
status trigger blender summary
register is set.
Bit B10 decimal value: 1024.
B11
status.operation.instrument.TRIGGER_TIMER
status.operation.instrument.TRGTMR
Set bit indicates one or more
enabled bits for the operation
status trigger timer summary
register is set.
Bit B11 decimal value: 2048
B12
status.operation.instrument.DIGITAL_IO
status.operation.instrument.DIGIO
Set bit indicates one or more
enabled bits for the operation
status digital I/O summary register
is set.
Bit B12 decimal value: 4096
B13
status.operation.instrument.TSPLINK
Set bit indicates one or more
enabled bits for the operation
status TSP-Link summary register
is set.
Bit B13 decimal value: 8192
B14
status.operation.instrument.LAN
Set bit indicates one or more
enabled bits for the operation
status LAN summary register is
set.
Bit B14 decimal value: 16,384
B15 Not used Not applicable.
As an example, to set bit B1 of the operation status instrument summary enable register, set
status.operation.instrument.enable = status.operation.instrument.SMUA.
In addition to the above constants, operationRegister can be set to the numeric equivalent of the bit to set.
To set more than one bit of the register, set operationRegister to the sum of their decimal weights. For
example, to set bits B1 and B10, set operationRegister to 1,026 (which is the sum of 2 + 1024).
