Lpc2000

Hi,

This is not the checksum I mean. This is the checksum for validating
for valid user code and startup with the application and not with the
boot block. The calculation of this checksum is described in the user
manual. 
The checksum I mean is the one to be sent after sending uuencoded
lines to the device.
