Fig. 3: Memory area 000000..00FFFFh. This page is accessed when
address bits 16..23 (20..23 not output by the controller) are all
zero. The addresses 00xxxxh access this page. However,
10xxxxh accesses the complete external page 0.
In User Mode 1 (sub-mode "a" and "b") RAM 0 is mapped to page 0, so RAM 0 can be
accessed as well on external page 0 as within the external I/O area and upper area on absolute
page 0. In return for it Module 0 is mapped on page E. In sub-mode "b" this area is enlarged to
128 KB so that Module 1 could be accessed on page F.
The RAM on page 0 (in User Mode 1) might be used for accessing the external I/O-area. A
program fixed on ROM (including its own interrupt vector table and plugged as Module 1)
could be started in User Mode 1b by pressing User Reset button.
The low active signal EXP (expansion) set by the Evaluation Board peripherals might be used
to select the remaining external memory area not occupied by the board itself. These signals
( EXP, the module chip selects CSx , the address bus provided by the Evaluation Board and the
address/data bus, the bus control signals provided by the controller itself) might be used for
system expansions.
Eight control bank register and four switches control the evaluation board and its memory
mapping. Three jumpers are needed for further functionality. The control bank register resides
at physical page 7 (see fig. 4). The four switches are placed left beside the Power and the User
RUN LED (see fig. 1).
