2 DEVICE ARCHITECTURE
2.1 CORE ARCHITECTURE
The ST9 Core or Central Processing Unit (CPU)
features a highly optimised instruction set, capable
of handling bit, byte (8-bit) and word (16-bit) data,
as well as BCD and Boolean formats; 14 address-
ing modes are available.
Four independent buses are controlled by the
Core: a 16-bit Memory bus, an 8-bit Register data
bus, an 8-bit Register address bus and a 6-bit In-
terrupt/DMA bus which connects the interrupt and
DMA controllers in the on-chip peripherals with the
Core.
This multiple bus architecture affords a high de-
gree of pipelining and parallel operation, thus mak-
ing the ST9 family devices highly efficient, both for
numerical calculation, data handling and with re-
gard to communication with on-chip peripheral re-
sources.
2.2 MEMORY SPACES
There are two separate memory spaces:

arate memory areas, including the internal ROM,
internal RAM and external memory are mapped
in this common address space. The total ad-
dressable memory space of 4 Mbytes (limited by
the size of on-chip memory and the number of
external address pins) is arranged as 64 seg-
