Lpc2000

Hi, Mr Jaya,
Had eMail you the 8KB LPC2103 bootloader image.
Please help to disassemble the first few line to find out if JTAG
is default as ON or OFF, on the LPC2103.

Please do NOT use any new things like CSPR to confuse me. I do
NOT have the type of your brain power and could only analyze
hardware bit-by-bit. I'm only interested in the question of
*** On LPC2103, Is JTAG default as OFF or ON ***. 
I do NOT care what's CSPR.

Main purpose is to find a new philips chip capable of shoot
down all your theories:
1) External JTAG breaking in before Booloader could disables the
   JTAG port fast enough (Some 30-70 clocks thing)..??
2) Philips planted a Trojan horse inside the bootloader..??
3) Crashing of bootloader by some undocumented ISP commands..??
4) Exception interrupts are not handled correctly by the
   bootloader..??

To me, Only item 1 is critical.   Items 2,3,4 are software problems
only and the best you could do is crashing the bootloader.  There
are tons of other ways to hang up the CPU at any time, any board.
But what you get would be some <0.0000001% chances of reading
out the protected code.

I trust you for not cheating by modifying the rom image....  :)
Regards
