High Battery Voltage.
The value written to this register sets high battery voltage. VBATH must be greater than
or equal to VBATL. The value may be set between 0 V (0x00) and –94.5 V (0x3F) in
1.5 V steps. Default value = –75 V. For Si3211, VBATH must be set equal to externally
supplied V
Read returns zero.
Low Battery Voltage.
The value written to this register sets low battery voltage. VBATH must be greater than or
equal to VBATL. The value may be set between 0 V (0x00) and –94.5 V (0x3F) in 1.5 V
steps. Default value = –24 V. For Si3211, VBATL must be set equal to externally supplied
