In a p system each part (RAM, ROM, I/O) has a unique set of numbers. The allocation of these numbers is usually stated in the form of a memory map. This is a plot of data bus against address.
E.g. Calculate the height and width of the memory map for a 68Hc11 p.
Since address = A0 -> A15 data = D7 -> D0 The maximum address is given by: - 216 -1 = 65535 bytes @ 64Kbytes (K = 1024). We can draw this in the form of a memory map difficult i.e. data width horizontal and address vertically as shown below: -
