* = condition, enable, event, ntr or ptr
Attribute Operation measurement event register set.
Usage Reads condition, enable, event, NTR and PTR registers:
operreg = status.operation.measuring.condition
operreg = status.operation.measuring.enable
operreg = status.operation.measuring.event
operreg = status.operation.measuring.ntr
operreg = status.operation.measuring.ptr
Writes to enable, NTR and PTR registers:
status.operation.measuring.enable = operreg
status.operation.measuring.ntr = operreg
status.operation.measuring.ptr = operreg

• This attribute is used to read or write to the operation measurement registers.
Remarks
• 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 0, and the most significant bit is bit 15.
For example, assume value 6 is returned for the enable register. The binary
equivalent is 0000000000000110. This value indicates that bit B1(SMUA) and bit B2
(SMUB) are set.
• The used bits of the operation measurement registers are described as follows:
• Bit B1, SMUA – Set bit indicates the enabled MEAS bit for the SMU A operation
register is set.
• Bit B2, SMUB – Set bit indicates the enabled MEAS bit for the SMU B operation
register is set.
Details See "Operation Event
Example Sets the SMUA bit of the operation measurement enable register:
status.operation.measuring.enable =
status.measuring.calibrating.SMUA
to one of the following values:
can also be set to the decimal weight of the bit to be set. Examples:
