Does the nRF51822 have a SysTick timer?

Question

I wanted to use the SysTick timer for timing in my application, but even when writing a handler and trying to set it up, it doesn't seem like the interrupt is ever triggered. Does the chip even have such timer?

Unfortunately for you, we've chosed to not implement a SysTick timer in the nRF51822. This is an optional feature in Cortex-M0, and since we believe that all use cases are covered by the other timers, we chose to not implement a separate SysTick timer. 
 If you need a high-frequency timer, you should be able to use one of the normal timers for that, while if you need a low-power solution, you should look into the RTC timers.
