Audio Interface Module (AIM)
17.5
There are a total of three serial audio interfaces. Each interface can handle Philips I
protocol. Interface 1 is a receive/transmit interface. Interface 2 is transmit only, Interface 3 is a receive
only. Every serial audio interface block has a 32-bit configuration register associated with it.
Inversion of the LRCK clock only operates correctly on a slave receiver, therefore IIS3. If IIS1 is being
used for transmit and receive in master mode then LRCK will be inverted on both the input and the output.
Thereby cancelling the effect.
The SCLK and LRCK signals for each I
generated internally (outputs). See
Figure 17-2
description of the bit fields.

Each of the three I
or Sony EIAJ mode with either 32, 36, or 40 bits per word clock. Timing
diagrams describing each of these modes are given in the following
sections. The frequency of the clock and data signals is programmable, as is
the inversion of the bit clock (SCLK) or word clock (LRCK) for each I
interface.
