Help¶

Turn on measurement of radio ISR latency, CPU usage and generation of controller event with these profiling data. The controller event contains current, minimum and maximum ISR entry latencies; and current, minimum and maximum ISR CPU use in micro-seconds.

Direct dependencies¶

BT_LL_SW_SPLIT && BT_CTLR && BT_HCI && BT

(Includes any dependencies from ifs and menus.)

Defaults¶

No defaults. Implicitly defaults to n.
