The SAM3U4E programmable clock output is used to generate the WM8731 master clock (MCLK). The
SAM3U4E ODT (On-Die Termination) feature guarantees a signal integrity on this clock line without the
need for external discrete components.
WM8731 pin 21 MODE is pulled down by default; this configures the device as a TWI device for internal
register access.
Pin15 CSB is pulled up, which sets its TWI address as 33 [0x0011011].
The WM8731 digital interface works in slave mode on the SAM3U4E Synchronous Serial Controller
(SSC) interface, which means that Codec digital audio bit clock and ADC/DAC left/right control clock are
to be generated by the SAM3U4E.
