buffered serial port (BSP)

An on-chip module that consists of a full-duplex, double-buffered serial port interface and an autobuffering unit (ABU).

The double-buffered serial port of the BSP is an enhanced version of the standard serial port interface. The double-buffered serial port allows transfer of a continuous communication stream (8-,10-,12- or 16-bit data packets). Status and control of the BSP is specified in the BSP control extension register (SPCE).
