CONFIG_CLOCK_CONTROL_NPCX_EXTERNAL_SRC

Generate LFCLK by on-chip Crystal Oscillator

Type: bool

Help

When this option is enabled, the internal 32.768 KHz clock (LFCLK)
is generated by the on-chip Crystal Oscillator (XTOSC).
This includes an on-chip oscillator, to which an external crystal
and the related passive components are connected.

Direct dependencies

CLOCK_CONTROL_NPCX && CLOCK_CONTROL

(Includes any dependencies from ifs and menus.)

Defaults

No defaults. Implicitly defaults to n.
