The basic idea is to configure the SPI or SSP as a slave device and 
supply the clock and control signals.  These can be derived from 
timers / external logic as required.  There are some restrictions if 
you require continuous back-to-back transmission.  See ch.12&13 in 
user manual.  The LPC provides the shift register, everything else is 
application specific.
