Signal/Connection Descriptions

and the Philips inter-integrated-circuit control (I2C) bus. The SHI supports either the SPI or I2C bus protocol, as required, from a

slave or a single-master device. To minimize DSP overhead, the SHI supports single-, double- and triple-byte data transfers. The

SHI has a 10-word receive FIFO that permits receiving up to 30 bytes before generating a receive interrupt, reducing the overhead

for data reception. For more information on the SHI, refer to DSP56371 User Manual, Section 7, Serial Host Interface.

2.5.6 Digital Audio Transmitter (DAX)

The DAX is a serial audio interface module that outputs digital audio data in the AES/EBU, CP-340 and IEC958 formats. For

more information on the DAX, refer to DSP56371 User Manual, Section 10, Digital Audio.

Signal/Connection Descriptions

3.1 Signal Groupings

The input and output signals of the DSP56374 are organized into functional groups, which are listed in Table 1. and illustrated in

Figure 2.

The DSP56374 is operated from a 1.25 V and 3.3 V supply; however, some of the inputs can tolerate 5.0 V. A special notice for

this feature is added to the signal descriptions of those inputs.
