Hi,Hitesh

You can reference http://www.hilosystems.com/.

I use ALL-P3 programmer to program ISP into 922 chip.
ALL-P3 programmer support this function.

ISP programs are not the same between lpc932 and lpc922.

I also have successfully used an Prolific chip(PL-2303)  USB to RS232  cable with Flash Magic.

I am not care to erase lpc922.
So, I want to use parallel programmer to reprogram.
Where is  ISP hex file for lpc922.
Are they the same between lpc932 and lpc922 ?

I don't know where is version 1.3 source file.
Andy say, version 1.3  source file is not opened.

I suggest that you can disassemble the version 1.3 hex file.
And, reference version 1.2 source file, reconstruct the version 1.3 source file.
It's a good idea.

Usually, When you use a USB-Serial Cable.
Baud Rate can't speed up too high.
So , You can try 9600bps, change T1 & T2 for adaptively, High speed communications.

I have email AN10258_2.pdf to you.

In http://www.promax.se/download/data/Semi/Philips/Micro_controller/lpc90x/ is vesion 1.2.

It has some bugs.

I have successfully used an FTDI chip(FT232AM/BM) USB  to RS232 cable with Flash Magic.

Thanks Andy.

But, I mean that Why add t1 and t2 ?
What relation does the t1 & t2 have with the ISP?
