CONFIG_CLOCK_CONTROL_NRF_K32SRC_BLOCKING

Blocking 32KHz crystal oscillator startup

Type: bool

Help

Clock control driver will spin wait in CPU sleep until 32KHz crystal oscillator starts up. If not enabled, RC oscillator will initially start running and automatically switch to crystal when ready.

Direct dependencies

CLOCK_CONTROL_NRF_K32SRC_XTAL && CLOCK_CONTROL_NRF && !CLOCK_CONTROL_NRF_FORCE_ALT && CLOCK_CONTROL

(Includes any dependencies from ifs and menus.)

Defaults

No defaults. Implicitly defaults to n.
