+         *
+         *   For channel selection involving band switching, and to ensure
+         *   smooth tuning to the desired channel without causing
+         *   unnecessary charge pump action, it is recommended to consider
+         *   the difference between wanted channel frequency and the
+         *   current channel frequency.  Unnecessary charge pump action
+         *   will result in very low tuning voltage which may drive the
+         *   oscillator to extreme conditions.
+         *
+         * Set this flag to 1 if this tuner needs this check.
+         *
+         * I tested this for PAL by first setting the TV frequency to
+         * 203 MHz and then switching to 96.6 MHz FM radio. The result was
+         * static unless the control byte was sent first.
