internal rtc implementation
I try to implement an internal RTC starting up from seconds timer.
I tried to use timer block and LFCLK but it make a timing violation warning of:
"Warning-1366: Setup time violation found in a path from clock ( CyHFCLK ) to clock ( CyHFCLK )."
when I tried to use Timercounter Block it make an error at build with:
"The listed clock input does not allow arbitrary signals for clocking and requires an input from the clock block. Update your design and rebuild."
plz advise about that and also if there is a BLE project that implement RTC mention it.
