1.3
The RS08 instruction set does not include extended addressing capability. There is a 64-byte window,
known as the paging window, from location $00C0 to $00FF, in the direct page reserved for paging access.
A page selection (PAGESEL) register ($001F) determines the corresponding 64-byte block in the memory
map for the paging window access. Upper memory access can be done by direct-page access through the
paging window area.
The entire accessible memory space for RS08 is 16K-bytes, and divided into 256 pages of 64-byte
memory. Programming the PAGESEL register ($001F) defines the page to be accessed through the paging
window.
