Lpc2000

Hi All

I'm planning to try out the LPC2114 and I have a question about the
bootloader and the state of the processors pins during this...

I have a multiplexer on UART 0 that can switch between a MAX232 for boot
loading or another serial device.

Channel A = RX
Channel B = TX

A+B Zero condition = serial device
A+B High condition = MAX232 for boot loading

A and B select lines are coupled directly to 

A = Trace sync (P1.20)
B = Trace PKT.3 (P1.19)

My philosophy is that when one holds the reset line low and drive P.14
low (boot enable) the processor will enter the bootloader with all its
pins set for tristate causing them to float except the Trace packet,
Trace sync, Pipe Status, etc. pins which has an internal pull up ...

The internal pull up should then be able to drive the multiplexers A+B
select lines high selecting the MAX232 chip for boot loading.  

According to the datasheet pins are tristated when reset is low but what
are their state when entering the bootloader? I would assume they where
all inputs? And that the internal pull ups would be enabled
automatically? 

Any thoughts? 

Best regards
Lasse
