The Real Time Counter (RTC) enables periodic interrupts at long intervals, or accurate mea-
surement of real-time sequences. The RTC is fed from a 16-bit prescaler, which is clocked from
the 32 kHz oscillator. Any tapping of the prescaler can be selected as clock source for the RTC,
enabling both high resolution and long timeouts. The prescaler cannot be written directly, but
can be cleared by the user.
The RTC can generate an interrupt when the counter wraps around the top value of
0xFFFFFFFF. Optionally, the RTC can wrap at a lower value, producing accurate periodic
interrupts.
