The datasheet for the LPC2101/02/03 can be found at;

www.standardics.philips.com/products/lpc2000/pdf/lpc2101_2102_2103.pdf

See Message number #9057 for the Press Release.

Hi Philips Marketing,
For the benefits of the 3rd party tool vendors (which ultimately benefits 
Philips), how about releasing some sort of standard header file description 
files for these new devices? It can be XML, header files for some 
compilers, whatever. Clearly the data is available internal at Philips 
(from the chip designers to doc writers to testers etc.), it would go a 
long way for us 3rd party tool vendors to support the devices quickly if 
Philips provides such files.

You may of course contact me directly with the files. I would love to add 
them to our next release.

Thanks.

The block diagram in the pdf shows "GENERAL PURPOSE GPIO" mapped to
"P0[31:0]" as well as "HIGH SPEED GENERAL PURPOSE GPIO" mapped to the
same "P0[31:0]". Does it mean the pins can be connected and controlled
by block connected to ARM memory bus or APB bus?

Hi,

the answer is YES, all of the above. The pins are connected to the APB 
bus by default for compatibility reasons but can be connected to the 
Local Bus (memory bus) as well.  For the "how" you could check the 
Users Manual of the LPC2148, which is the first of the Philips devices 
to use this methode.

Hi,

Is it possible to read pins with IO0PIN register even is they are mapped 
to other functions than the GPIO? As far as I know, this is not possible 
with the LPC2292. With the exception of the ADC pins, I don't know why 
the pins cannot always be connected to the IO0PIN register. This would 
be very usefull with reading the state of capture or interrupt pins for 
example.

I strongly second the request.  Not being able to directly read the 
state of Input Capture and Interrupt pins is a major hassle.

If this has not already been done, please consider this for future 
enhancements.

Hello Richard,

In response to your suggestion (and others'), we have prepared a 
general Header File for the LPC214x family.  I have posted it in the 
Files section.  We will also work on an LPC2101/2/3 file in the near 
future.  Thank you for your feedback.
