Clock Generator register overview
Some registers are write-protected to avoid inadvertent changes. Data can be
written to these registers only in a special sequence of instructions, so that the
register contents is not easily rewritten in case of a program hang-up.
Writing to a protected register is only possible immediately after writing to the
associated write protection register.
