AO_WS is the word-select or frame-
synchronization signal from/to the external D/A
subsystem. Each audio channel receives 1 sample
for every WS period.
Serial Data to external audio D/A subsystem for first
2 of 8 channels. The timing of the transitions on
these outputs is determined by the CLOCK_EDGE
bit in the AO_SERIAL register, and can be on a
positive or negative AO_SCK edge.

driver requires a 27-33
PNX1700 to match the board line impedance. This
resistor becomes a part of the voltage divider
necessary to drive the IEC958 isolation
transformer.
LAN_TX_CLK and LAN_RX_CLK have to be
connected to the RMII reference clock in RMII
mode.

AO_WS acts as an input. AO_WS is sampled on
the opposite AO_SCK edge at which
AO_SD[3:0] are asserted.
interface timing master, AO_WS acts as an
output. AO_WS is asserted on the same
AO_SCK edge as AO_SD[3:0].
