C Interface

The I

2

C bus on the DM642 is ideal for interfacing to the control registers of many

devices. On the DM642 EVM the I

2

C bus is used to configure the video encoder, video

decoders, and stereo Codec. An I

2

C ROM is also interfaced via the serial bus. The

format of the bus is shown in the figure below.

The addresses of the on board peripherals are shown in the table below.

2.5  SPDIF Interface

The McASP pins on the DM642 can be configured to operate as a SPDIF transmitter.
The DM642 EVM supports a single SPDIF output which is routed to RCA jack, J9. The
SPDIF  output pin is routed to a driver and filter circuit. When the SPDIF interface is
enabled the TLV320AIC23B codec is disabled.
