Hi, You might be right but the philips chip has sufficient 
code read protect mechanism build in.   This is some old topic..
There had been some heated discussions on this issue and so far 
the flash read protection had been proven cannot be bypassed and
JTAG port can been locked up properly.

Umm.. Not advisable to re-start another round of endless debating..
Everybody please better stop here before it is too late...  :)
Regards
