BSP (Buffered Serial Port) named in Omap McBSP (Multichannel Buffered Serial Port). This port provides a full-duplex direct serial interface between the device and other devices in a system such as other application chips ([http://en.wikipedia.org/wiki/Baseband#Digital_baseband_transmission digital base band]), audio and voice codec (power management device), etc. Because of its high level of versatility, it can accommodate to a wide range of peripherals and clocked frame oriented protocols. Omap have five BSP peripherals (McBSP1, McBSP2, McBSP3, McBSP4 and McBSP5). It can use seven signals:<br>

Omap have five BSP peripherals (McBSP1, McBSP2, McBSP3, McBSP4 and McBSP5). It can uses seven signals:<br>  *McBSP_DX: Transmited serial data.*McBSP_CLKX:&nbsp; Transmit serial clock.*McBSP_FSX: Transmit frame syncronization.*McBSP_DR: Received serial data.*McBSP_CLKR: Received serial clock. Only in MCBSP1.*McBSP_FSR:Received frame syncronization. Only in MCBSP1.

List of recommended usage (non exhaustive) per McBSP modules in the device:<br>

*McBSP1: Digital baseband (DBB) Data*McBSP2: Audio data with audio buffer and SIDETONE feature*McBSP3: Bluetooth voice data with SIDETONE feature*McBSP4: DBB voice data
