Hi Richard

In the future maybe but the present chip has a bug and the SPI only 
works if SSEL is configured for SPI use and pulled high.

After working that out I found it to be good as master.

I haven't found any details about problems as slave but did come to 
the conclusion that it is unusable - confirmed by someone else with 
the same wierd findings as my own in this group some time later. I 
have used SPI on many devices as master and as slave, have a good 
JTAG debugger, scopes and logic analysers but the LPC2106 as SPI 
slave beat me - its behaviour could not be explained, otherwise I 
wouldn't actually have used it as master communicating with an HCS12 
device (it was planed the other way round..).

Cheers
