title: NXP LPC1850 Clock Control Unit (CCU)

description:
  Each CGU base clock has several clock branches which can be turned on
  or off independently by the Clock Control Units CCU1 or CCU2. The
  branch clocks are distributed between CCU1 and CCU2.

    description:
      Which branch clocks that are available on the CCU depends on the
      specific LPC part. Check the user manual for your specific part.

      A list of CCU clocks can be found in dt-bindings/clock/lpc18xx-ccu.h.
