ML5805
REGISTER 0
Register 0 is a special register because some of the hardware is controlled directly from this register. Since those
specific bits are connected physically to active hardware, they must always be written first after power on. If Register 0
is not initialized first by the base band hardware, the ML5805 will not operate correctly.
