QHow do I connect the Real Time Clock (RTC) pins on Blackfin? What if I don't
want to use the RTC at all?
AFor lowest power consumption, it is best to follow the advice of EE-281:
Hardware Design Checklist for the Blackfin® Processors:
Real-Time Clock (RTC)
Does your design require a battery for continuous time information? If not,
RTC power to VDD_IO.
Ensure that an additional shunt resistor (1 MΩ to 10 MΩ) is present in the RTC
crystal circuit. If the RTC is not used, pull the RTXI pin low.
