Lpc2000

Additional note about Freescale MC9S12NE64 as TCP/IP co-processor.

I finally got around to checking the current consumption in 10M mode 
(as opposed to 100M). I measured almost exactly half the current 
consumption. ie. 125mA in 10M LAN mode / in 100M LAN mode it was 
about 250mA - all from 5V, altough after the 5V/3.3V regulator it is 
really 3V3 so approx. 0.4W at 10M and 0.8W at 100M. Is this good or 
bad?????
