Lpc2000

Hello All,

I have not used any of the LPCxxx devices before.  I am considering 
using an LPC2138 in an application which must read data from an 
ADS1271 24bit A/D using an SPI interface.

In looking at the SSP specification for the LPC2138, it can handle a 
maximum frame size of 16 bits.  Does anyone know of a way to extend 
this to 24bits without CPU intervention? Has anyone done something 
similar?  The ADS2171 will have a 100kHz data rate, so I'm worried 
about having interrupts on a Byte by Byte basis, as that would be a 
300kHz interrupt rate (100kHz X 24/8).

Thanks for any help.
Jeff

p.s. Great user group.  Lots of good info.
