LPC4330 part ID

hi,

I read this in the user manual of lpc43xx ,"IAP commands are only supported for parts with on-chip flash. "

lpc4330 has no flash on it, so how do lpc4330 read part identification number?

hi,

Thank you very much for your letter.

I learned that a part id can be read from an otp memory bank0, but the otp Driver does not provide an API.Here's what the user manual says: "For flashless parts only: The unique part ID can be read from OTP bank 0, words 0 to 3 at memory location 0x4004 5000."

How can I access this address?
