+ * U7.1 format is defined as (ddddddd+1) + (h*.5)

+ * So:

+ * however we can't do fractional arithmetic ... these are integers!
+ * So we normalize by shifting the result left 1 bit, and extracting
+ * ddddddd and h directly to the returned u8.
+ * divider = 2*(ref/freq);
+ * We want to
+ * preserve 7 bits of divisor and one bit of fraction, in 8 bits, as well as
+ * subtract one from ddddddd. Since we computed ref*2, the dddddd is now nicely
+ * situated in the upper 7 bits, and the h is sitting there in the low order
+ * bit. To subtract 1 from ddddddd, just subtract 2 from the 8-bit number
+ * and voila, upper 7 bits are (ref/freq-1), and lowest bit is h. Since you

+ * and lowest order bit is a fraction.
+ * from the book, U7.1 is (ddddddd+1) + (h*.5)
+ * To normalize to an actual number, we might do this:
+ * ((d>>7+1)&0x7f) + (d&1 >> 1)

+ * Since we can't express the fractional bit, we need to multiply it all by 2.
