Hello Randy, Karl and other LPC2000 fans,

The most current revision of the LPC214x User Manual has been
uploaded into the files section of this forum (UM10139_1.ZIP). It
will take several days for this file to be available for download
from the official Philips website. Since this is quite a big one
(original size 10MB, zipped 3.8MB) we would remove it from Yahoo
files later so that other content can be posted.

In this document you will find full description of the Fast GPIOs,
enhanced AD features (i.e. dedicated result registers for every
input), UART improvements (fractional baud rate generators,
autobauding, full hardware implementation of the CTS/RTS flow
control) and of course the USB device chapter. Enjoy!

Regards,

Philips Apps Team
