High Battery Switch Threshold.
Programs the voltage threshold for selecting the high battery supply (VBATH).
Threshold is compared to the RING lead voltage (normal ACTIVE mode) plus the
VOV value. 0 to 160.173 V range, 4.907 mV/LSB, 628 mV effective resolution.
Battery Tracking Filter Coefficient.
Programs the digital low-pass filter block that filters the voltage measured on the
RING lead when battery tracking is enabled.
Low Battery Switch Threshold.
Programs the voltage threshold for selecting the low battery supply (VBATL). Thresh-
old is compared to the RING lead voltage (normal ACTIVE mode) plus the VOV
value. 0 to 160.173 V range, 4.907 mV/LSB, 628 mV effective resolution.
