And why ? Because of using the I2C ? Or because the LM4947 disturbs you JTAG
port ? Or ...
I think these are too less details to say something about the error or try
to reproduce it.

hello,
I would like to report a very strange bug I found:
I'm working on a LPC2103 based system. The LPC communicates with a
classD audio amplifier from NS: LM4947.
We found the following bug:
It's impossible to programm the LPC more than on time using the JTAG
We realized that it is impossible to reprogram the LPC if the LM4947
is ON.
