ICP programming error

[muhyin]

Dear All,

i'm working on LPC913 and got a problem to read the device signature of my LPC913.
i got all FF, i have checked pin configuration and the pins are connected as mentioned in application note document.
when i look into RESET pin, there is no burst 7x high-low signal.

has anyone experienced with it, could somebody help me. thanks

I have followed the instruction of "In Circuit Programming (ICP) Specifications" and "AN10258 Rev. 02 — 21 October 2004" documents.
is it problem with supply or what?


best regards
muhyin
