The Nordic Semiconductors nRF51822 is a NXP ARM Cortex-M0 processor with a built-in Bluetooth radio. It supports Serial Wire Debug, but All Nordic publications refer to Segger j-Link debug interface devices. I would like to use one of my Ulink 2 pods, but SWD defines three signals - SWDIO, SWDCLK and RESET. However, on the nRF51822 Pin 23 is SWDIO/nRESET and there is no separate RESET pin. Is the RESET signal required by the ULINK 2 or is it an output from the ULINK 2 that I can simply ignore?
