Lpc2000

If P1.20 is '1', set to not use the trace port after reset but p1.26
is low to enable debugging, can p1.16 to p1.25 be used as general
purpose I/O ports during debug? The APP Note 10255 seems to apply to
parts with only Port 0 not Port 1, or does the same App Note apply on
the LPC2131. Is there any way to program a new device during
production other than use to ISP method, i.e. are there any JTAG Flash
tools available? I can't seem to locate a BSDL file for the part any
ideas where that can be found?
