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).
- McBSP_DX: Transmited serial data.<br> - McBSP_CLKX: Transmit serial clock.<br> - McBSP_FSX: Transmit frame syncronization<br> - McBSP_DR: Received serial data.<br> - McBSP_CLKR: Received serial clock<br> - McBSP_FSR:Received frame syncronization.<br>
