using SWO with nRF52

[Andrew]

The documentation indicates that the new nRF52 supports SWO for debug.

Is there any simple example code to get this working?

Last time I did anything with a Cortex-M4F the function to send a single character was

__STATIC_INLINE uint32_t ITM_SendChar (uint32_t ch)

Which worked in the Keil uVision compiler and sent a single character over the Instruction Trace Module channel #0.
