Common Mode Voltage.
Programs the common mode voltage between the TIP lead and ground in normal
polarity (between RING and ground in reverse polarity). The recommended value is 3 V,
but can be programmed between 0 and 63.3 V. 4.907 mV/LSB, 1.005 V effective resolu-
tion,
Loop Voltage Sense Value.
Holds the realtime measured loop voltage across TIP-RING. 0 to 160.173 V range,
4.907 mV/LSB, 628 mV effective resolution (251 mV effective resolution for VLOOP <
64.07 V.
Scaled Battery Voltage Measurement.
Reflects the battery voltage measured through the monitor ADC. 0 to 160.173 V
range, 4.907 mV/LSB, 628 mV effective resolution. (251 mV effective resolution for
VBAT < 64.07 V).
