Audio Codec Interface Waveforms
Figure 16 and Figure 17 show the timing for the
ACI. Transmit data is clocked on the rising edge of
ACBITCLK (whether transmitted by the LH7A404 ACI
or by the external codec chip); receive data is clocked
on the falling edge. This allows full-speed, full duplex
operation.
