invalid address (LPC3250)

Hi
I work with an LPC3250 and I realized that I can read or write into memory address which supposed to be invalid without any problem (for example 0x04000000, the user manual mentions that writing into this address has no effect).
can you give me an explanation? thanks

  • thank you for the explanation.
    the problem is that when I do a DMA transfer with undefined addresses it works correctly (I did it by accident, I used the address 0x00800000 instead of 0x08000000 and the address 0x00803000 instead of 0x08003000) but the transfer fails with defined addresses (0x08000000 and 0x08003000). thank you for the help
