Lpc2000

Hi Gus,
Yes, it does work, however, note the following:
 
It's only supported on 64-pin/144-pin LPC2000 devices with a Boot Loader ID
>= 1.6  (you can check your device's ID using Ashlings FlashLPC utility or
the Philips FlashISP utility). 
 
Code read protection is enabled by programming the flash address location
0x1FC (User flash sector 0) with value 0x87654321 (2271560481 Decimal). If
Read Protection is enabled then the device has to be fully erased (thus
disabling Read Protection) before it can be re-programmed. In addition, you
will not be able to "connect" to the device via JTAG, hence, erasing must be
done using FlashLPC/FlashISP.
