Signal/Connection Descriptions
implement the Motorola SPI serial protocol. The ESAI consists of independent transmitter and receiver
sections, each with its own clock generator. It is a superset of the DSP56300 family ESSI peripheral and
of the DSP56000 family SAI peripheral. For more information on the ESAI, refer to DSP56371 User ’s
Manual, Enhanced Serial Audio Interface (ESAI) section.
2.5.4
Enhanced Serial Audio Interface 1 (ESAI_1)
The ESAI_1 is a second ESAI interface. The ESAI_1 is functionally identical to ESAI. For more
information on the ESAI_1, refer to DSP56371 User ’s Manual, Enhanced Serial Audio Interface (ESAI_1)
section.
2.5.5
Serial Host Interface (SHI)
The SHI is a serial input/output interface providing a path for communication and program/coefficient data
transfers between the DSP and an external host processor. The SHI can also communicate with other serial
peripheral devices. The SHI can interface directly to either of two well-known and widely used
synchronous serial buses: the Motorola serial peripheral interface (SPI) bus and the Philips
inter-integrated-circuit control (I 2 C) bus. The SHI supports either the SPI or I 2 C 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 ’s Manual, Serial Host Interface section.
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 ’s Manual, Digital Audio
section.

Signal/Connection Descriptions
Signal Groupings
The input and output signals of the DSP56374 are organized into functional groups, which are listed in
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.
