will make the ADAU1772 boot from the E2PROM when it
powers up.

The Power-Down Header J15, labeled

on the silkscreen
of the board, provides access to the power-down pin on the
ADAU1772. Put a jumper on the header to power down all
analog and digital circuits. Before enabling
/PD
be sure to mute
the outputs to avoid any pops or clicks when the IC is powered
down.
