6LVSP
Loop Voltage Sense Polarity.
This register reports the polarity of the differential loop voltage (VTIP – VRING).
0 = Positive loop voltage (VTIP > VRING).
1 = Negative loop voltage (VTIP < VRING).
5:0
LVS[5:0]
Loop Voltage Sense Magnitude.
This register reports the magnitude of the differential loop voltage (VTIP–VRING). The
range is 0 V to 94.5 V in 1.5 V steps.
