The WM8722 controls the device functions using 15 program registers, each of which is 16-bits long.
These registers are all loaded via the serial control interface in either 2 or 3-wire mode.
There are two type of control word; either TFREQ, the tone frequency word, which is a single address
bit followed by 15 data bits, or other types, which have 6 address bits, and 10 bits of data. Other
types have the lead address bit inverted compared to TFREQ words, allowing use of a single write to
load the required frequency.
