Lpc2000

Hi, 

Help!!  I'm using lots of LPC2124, but not LPC213x yet.
Somebody pls.. pls.. confirm problem related to LPC213x only.
(something like due to moving port I/O to local bus and add
address comparator so that prefetch queue not flushed 
=> for high speed I/O port toggling.   Or whats ever)

Many Thanks and Best Regards   /MH
