Can anybody say how to interface the EPROM(64KB) with P89c51RD2HBP so that when the code limit exceeds 64KB in the philips controller the exceeded segment should goto the EPROM.
Once you go for code banokng the process will snowball, first you lose 16 port pins (and - most likely have to make some MMIO) which again increases your code size, then you will find other areas where the effect of banking result in growth.
The code memory size has been increased to accomodate the code to handle the increased code memory.
yes, you have the size, but you still need to write all that additional stuff.
