status.measurement.reading_overflow.*

This attribute contains the measurement event reading overflow summary register set.

Type TSP-Link accessible Affected by Where saved Default value

Attribute - - - - - - - -

.condition (R) Yes Not applicable Not saved Not applicable

.enable (RW) Yes Status reset Not saved 0

.event (R) Yes Status reset Not saved 0

.ntr (RW) Yes Status reset Not saved 0

.ptr (RW) Yes Status reset Not saved 2 (All bits set)

Usage

measurementRegister = status.measurement.reading_overflow.condition

measurementRegister = status.measurement.reading_overflow.enable

measurementRegister = status.measurement.reading_overflow.event

measurementRegister = status.measurement.reading_overflow.ntr

measurementRegister = status.measurement.reading_overflow.ptr

status.measurement.reading_overflow.enable = measurementRegister

status.measurement.reading_overflow.ntr = measurementRegister

status.measurement.reading_overflow.ptr = measurementRegister

measurementRegister

The measurement reading overflow summary register status. 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 reading overflow 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 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:
