I use LPC2468.

I has write some code to control PWM, and I set the PCON = 0x2, so the
system enter power down mode, and then, I cann't download any program
to this chip, because every time this board power up, it enter power
down mode, so I cann't connect jtag. Anybody has any method to solve
this problem?

Pull P2.10 low, and do a hard reset to force the bootloader to remain
in control after reset. That way, your code will not execute and put
the chip into Power Down mode.

Hello,

One option is erase the device via Serial using the Flash Magic.
