Lpc2000

I coudn't agree more.

Also this is a problem Philips should have used the bootloader select
pin as a separate pin that has nothing to do with on chip functions.

It's a pain in the ass that P0.14 (DCD) on the full modem interface has
to be taken special care of when connecting to a modem through
multiplexers and such expensive garbage. 

I've used the LPC2106 a few times and flew back to AVR at an instant
because of this and I'm now looking for other ARM controllers.

You may be happy, I'm rather dismayed that this works.  It means that
P0.14 
cannot be used in an application since it implies that if you get a for 
instance watchdog reset while P0.14 happens to be low rather than 
restarting the application you will enter ISP mode.  Dangerous,
Dangerous....

The other processors I've used that use this required that an external 
reset be used before entering any special modes (such as ISP) in order
to 
prevent such behaviour.  You did have to be careful about the reset
state 
but that's something you needed to be careful of anyway.
