* = condition, enable, event, ntr or ptr
Attribute Operation calibration event register set.
Reads condition, enable, event, NTR and PTR registers:
Usage
operreg = status.operation.calibrating.condition
operreg = status.operation.calibrating.enable
operreg = status.operation.calibrating.event
operreg = status.operation.calibrating.ntr
operreg = status.operation.calibrating.ptr
Writes to enable, NTR and PTR registers:
status.operation.calibrating.enable = operreg
status.operation.calibrating.ntr = operreg
status.operation.calibrating.ptr = operreg
Set operreg to one of the following values:
0
status.operation.calibrating.SMUA
status.operation.calibrating.SMUB
operreg
To set bit B1 (SMUA), set
To set bit B2 (SMUB), set
To set both bits, set operreg to the sum of the decimal weights of both bits.
To set bits B1 and B2, set operreg to 6 (2 + 4).
Remarks • This attribute is used to read or write to the operation calibration 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 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 calibration registers are described as follows:
Bit B1, SMUA – Set bit indicates the enabled CAL bit for the SMU A operation
•
register is set.
Bit B2, SMUB – Set bit indicates the enabled CAL bit for the SMU B operation
•
register is set.
Details See "Operation Event
Example Sets the SMUA bit of the operation calibration enable register:
status.operation.calibrating.enable =
status.operation.calibrating.SMUA
