I am working in LS2088A based project. I have doubt in RTC. There exist a pin TA_BB_RTC - pin K19. In datasheet, it is referred as reverved and given a note to connect it ground. But, Is this anything regarding the optional RTC clock? Should we give the provision of optional Oscillator?
If not, why is the name TA_BB_RTC. Please clarify.
TA_BB_RTC has been de-featured. Since there were customers that have already designed with the pin name, it was decided to keep the pin name.
Note 15 is correct. New designs should disregard the reference board on this and be implemented in accordance with the processor's Data Sheet.
