JP5 Header Serial Interface Test Points
The JP5 Header provides access to the AMBE-3000™ Vocoder chip’s Multichannel Buffered Serial Port
(McBSP) Interface. When the HDK is in Codec Mode the McBSP interface is used for speech data and
it is not available for packet data. In Packet Mode the McBSP interface is used for both speech data
and packet data.
