description: |
  The System Management Unit is described in user's manual R19UH0037EJ1000_SMU.
  This is not a clock provider, but clocks under SMU depend on it.

    description: |
      Function block with an input mux and a divider, which corresponds to
      "Serial clock generator" in fig. "Clock System Overview" of the manual,
      and "xxx frequency division setting register" (XXXCLKDIV) registers.
      This makes internal (neither input nor output) clock that is provided
      to input of xxxGCLK block.
