Usage
measurementRegister = status.measurement.condition
measurementRegister = status.measurement.enable
measurementRegister = status.measurement.event
measurementRegister = status.measurement.ntr
measurementRegister = status.measurement.ptr
status.measurement.enable = measurementRegister
status.measurement.ntr = measurementRegister
status.measurement.ptr = measurementRegister
measurementRegister
The measurement event register's status. A zero (0) indicates no bits set (also
send 0 to clear all bits); other values indicate various bit settings.
Details
These attributes are used to read or write to the measurement event 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. This attribute is used to read or write to the
measurement event registers. For example, assume value 257 is returned for the enable register. The binary
equivalent is 0000 0001 0000 0001. This value indicates that bit B0 (VLMT) and bit B8 (BAV) are set.
