Main clock source

Type: bool

Help

Selects the clock that the main clocks, such as the CPU clock and AHB clock, will be derived from.

Direct dependencies

(SOC_SERIES_SAMD20 || SOC_SERIES_SAMD21 || SOC_SERIES_SAMR21) && SOC_FAMILY_SAM0

(Includes any dependencies from ifs and menus.)

Defaults

No defaults. Implicitly defaults to the first (visible) choice option.

Choice options

• SOC_ATMEL_SAMD_XOSC32K_AS_MAIN

• SOC_ATMEL_SAMD_XOSC_AS_MAIN
