Lpc2000

Hi,

the LPC2148 (LPC2138 with USB) has fast I/O.  In an assemler test 
program we were able to switch the ports with a frequency of CPU/4, 
ergo 15 MHz.

Because this chip also has an improved UART, it is possible to reach 
even 115200 Baud with 60 MHz, no need to use 14.756 MHz any more if you 
prefer even frequencies (like I do).  In fact for the USB you might 
want to use 12 MHz external anyhow. 

Cheers, Bob
