Please point me to the schematics that are needed to run the Kinetis when otherwise not powered, as a time-of-day clock. Ie, what parts of the processor need to be powered from a coin battery? Power switching circuits?
Is there an App Note available on implementing a time-of-day clock on Kinetis? If not, it would be a good topic. Hint, Hint. This is going to be a recurring design element for a lot of engineers.
Does MQX have any functionality intended for use with the Real-Time-Clock / Time-of-Day to implement a clock-calendar?
I see that the KwikStik has a 32KHz XTAL. Is that board complete enough to function as a battery-backed time-of-day clock? Is there example code that comes with the board to implement time-of-day functionality?
