Re: IAP successfully used in LPC2119/2129/2194/2292/2294?

I took a long look at your reply and the message reference on the 
bug. Honestly I haven't experienced this bug before. Are all 
lpc2114/19/29 chips affected?

Yeah, I see it in the manual. It's very wierd that I still got good 
writes & erases when I passed in frequencies other than cclk with 
PLL enabled. Sorry to be a thorn though but can someone explain why 
and/or how PLLs can affect IAP alternate writes & erases?

Thanks
