Serial Communication Interfaces – McBSP LP Signals Description
The multichannel buffered serial port (McBSP) provides a full-duplex direct serial interface
between the device and other devices in a system such as other application chips (digital base
band), audio and voice codec, etc. Because of its high level of versatility, it can accommodate to
a wide range of peripherals and clocked frame oriented protocols.
