/*
* The BLE SW link layer defines 10 GPIO pins for debug related
* information (but really only uses 7 pins). Zephyr has a block of
* 10 GPIOs routed to J2 odd pins 1-19 (inside bank of J2).
*
* Mapping:
*
* J2.1 : DEBUG_CPU_SLEEP
* J2.3 : DEBUG_TICKER_ISR, DEBUG_TICKER_TASK
* J2.5 : DEBUG_TICKER_JOB
* J2.7 : DEBUG_RADIO_PREPARE_A, DEBUG_RADIO_CLOSE_A
* J2.9 : DEBUG_RADIO_PREPARE_S, DEBUG_RADIO_START_S, DEBUG_RADIO_CLOSE_S
* J2.11 : DEBUG_RADIO_PREPARE_O, DEBUG_RADIO_START_O, DEBUG_RADIO_CLOSE_O
* J2.13 : DEBUG_RADIO_PREPARE_M, DEBUG_RADIO_START_M, DEBUG_RADIO_CLOSE_M
* J2.15 : DEBUG_RADIO_ISR
* J2.17 : DEBUG_RADIO_XTAL
* J2.19 : DEBUG_RADIO_ACTIVE
