Hello Everyone!

Can anyone confirm that the content of the flash on the P89LPC932 is $00 instead of $FF after an erase operation (e.g. page erase)?

And if this is correct: Is it the same using ISP operations (e.g. using FlashMagic). An does "Fill unused Flash" mean writing $FFs instead $00s?

Thanks for your answer!

Yes, the LPC9xx devices contains 00H in all erased locations of Flash, regardless of the erase method.

Flash Magic fills the unused locations in Flash with FFH for the LPC9xx devices.
