Help¶

Enable PDN and CSN GPIO interface for the nRF21540. This allows
hardware designs using the nRF21540 to let the controller toggle
their state based on radio activity.

Direct dependencies¶

!SOC_SERIES_NRF51X && BT_LL_SW_SPLIT && BT_CTLR && BT_HCI && BT

(Includes any dependencies from ifs and menus.)

Defaults¶

No defaults. Implicitly defaults to n.
