32-Bit System-on-Chip
Audio Codec Interface (ACI) Timing
in Figure 39 and Figure 40. 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.
