Has anybody done this successfully?

On my LPC2114, I have tried doing a CPU reset by starting the 
watchdog and letting it expire.  But when it expires, the CPU just 
hangs, without restarting.  P0.14 isn't low, and it hasn't entered 
ISP mode.  I'm doing like this:

WDT->WDTC = PCLK_HZ/4; /* Timeout = 1 second */
WDT->WDMOD = 0x03;
WDT->WDFEED = 0xAA;
WDT->WDFEED = 0x55;

At this time I can see WDTV decrementing, and when it reaches zero, 
the system just hangs, and interrupt activity stops.
