Added nRF52 RTC based monotonic to the book
@@ -18,7 +18,8 @@ The trait documents the requirements for each method,
and for inspiration here is a list of `Monotonic` implementations:
- [`STM32F411 series`], implemented for the 32-bit timers
-- [`Nordic nRF52 series`], implemented for the 32-bit timers
+- [`Nordic nRF52 series Timer`], implemented for the 32-bit timers
+- [`Nordic nRF52 series RTC`], implemented for the RTCs
- [`Systick based`], runs at a fixed rate - some overhead but simple
- [`DWT and Systick based`], a more efficient `Systick` based implementation, but requires `DWT`
