Serial Port Signals
Figure 5-1 shows the SPORT signals (note that not all models have eight
SPORTs). Any 20 of these 32 signals can be mapped to digital audio
interface (DAI_Px) pins through the signal routing unit (SRU1). For more
information, see Chapter 4, Digital Audio/Digital Peripheral Interfaces.
