I've actually never noticed these before, but as far as I can see from Keil's documentation, these will only work either when having tracing enabled or when doing simulations.
Tracing is unfortunately not possible with the nRF51822, since it doesn't have the necessary hardware, and simulations are only possible on the core itself, with the standard Cortex M0, not with any of the Peripherals. I'm therefore not sure that's really useful.
For further information, I suggest that you contact Keil directly.
