Hello Niki,
The RADIO_IRQ, RADIO_BKGD and RADIO_RESET are not any pins or signals in MK10DN512ZVLL10 but the GPIOs used to control the IRQ, BKGD and RESET signals of the external MC13233. I would recommend you to take a look at MC1323x datasheet for further details about the device’s pinout and the mentioned signals.
MC1323x: http://cache.freescale.com/files/rf_if/doc/data_sheet/MC1323x.pdf
Furthermore, BeeKit includes several application examples for MC1323x. We recommend using such examples since they have been tested to work. You could modify such examples for your very specific use case if desired. Nevertheless, this is only for MC1323x and wireless connectivity products, not Kinetis K10. If you would like to initialize K10, you may use any other desired method.
Regards,
