* This is an example of how to initialize the Buffered Serial Port (BSP).
* The BSP is initialized to require an external CLK and FSX for
* operation. The data format is 16-bits, burst mode, with autobuffering
* enabled.

*LTC1403 timing from LCC28 socket board with 10MHz crystal.
*10MHz, divided from 40MHz, forced to CLKIN by 1403 board.
*Horizontal scale is 25ns/chr or 100ns period at BCLKR
*Timing measured at DSP pins. Jxx pin labels for jumper cable.
