A new audio input frame begins with a LOW-to-HIGH transition of SYNC. SYNC is
synchronous to the rising edge of BIT_CLK. On the immediately following falling edge
of BIT_CLK, UCB1400 samples the assertion of SYNC. This falling edge marks the
time when both sides of AC-link are aware of the start of a new audio frame. On the
next rising edge of BIT_CLK, UCB1400 transitions SDATA_IN into the first bit position
of slot 0 (‘Codec Ready’ bit). Each new bit position is presented to AC-link on a rising
edge of BIT_CLK, and subsequently sampled by the AC ’97 Controller on the
following falling edge of BIT_CLK. This sequence ensures that data transitions and
subsequent sample points for both incoming and outgoing data streams are time
aligned.
SDATA_IN’s composite stream is MSB justified (MSB first) with all non-valid bit
positions (for assigned and/or unassigned time slots) stuffed with 0s by the UCB1400.
SDATA_IN data is sampled on the falling edges of BIT_CLK.
