Just finding my way around the documentation for the LS1020A but cannot seem to find anything about the RTC (real-time clock) capability (or lack of it). Is there an RTC on chip that just requires an external battery, or what is the device type I need to connect to pin TA_BB_RTC?
1) On what pin should I provide my 32768Hz clock for the LS1020A, is it TA_BB_RTC?
2) At what voltage levels?
3) Which pin is the battery voltage supplied on, is it TA_BB_VDD?
4) What is the current draw from the battery pin.
I am not using the trust/SecMon feature if that question comes up.
