The address resolution for each memory bank base pointer is 64 Kbytes (16 bits). The base address
pointer is 10 bits. This gives a total addressable memory bank space of 16 M words.

Followings are several important features to note about the S5N8947 system memory map :
l
The size and location of each memory bank is determined by the register settings for “current bank
base pointer” and “current bank end pointer”. You can use this base/next bank pointer concept to set
up a consecutive memory map. To do this, you set the base pointer of the “next bank” to the same
address as the next pointer of the “current bank”. Please note that when setting the bank control
registers, the address boundaries of consecutive banks must not overlap. This can be applied even if
one or more banks are disabled.
