Lpc2000

I justed tested using the Keil Evaluation board (LPC2138) both the SPI
and the SSP configured as an SPI.  On both ports the SSEL line is set
as GPIO.  I even have the output of the SSEL pins toggling.  Using a
dual channel scope, the MOSI data is correct and within the clock
burst.  So far, I see both Perpherals behaving as specified in the
manual.  At this point, I'm not using interrupts or the FIFO logic in
the SSP.
