Googled and can't find a datasheet. Seems the payware website had
cleaned out the websites where you can access datasheets before.
What I needed:
typical schematic or description of CMOS battery back up 3.6V
rechargeable with 4069 IC and 82C206 (SiS, UMC, OPTi and C & T uses
this 82C206) specifically chipset's pin number for battery back up to
retain data and run clock.
I'm trying to troubleshoot typical motherboard that is not holding
CMOS data even I do have 3.6V battery power (already checked).
