An RTC based on a "268.435456 MHz" clock. The LEDs represent the seconds passed by default, but can display the top eight bits of the 28bit counter when the USER_BTN is held.
Note: The actual clock out of the PLL is 268.500000 MHz which is +240.44 ppm off of 268.435456 MHz. This will lose about 21 seconds/day in accuracy.
