Memor y organi sation
The CPU uses a Harvard architecture, so that memory is or
g
anised in two separated fields: pro
g
ram memory and
data memory. As both memory are separated, the central processin
g
unit can read/write data at the same time it
loads an instruction. Peripherals and system control re
g
isters are ma pped on data memory space. Pro
g
ram memory
is made in one pa
g
e. Data is made of several 256 bytes pa

Program memory
The pro

ram memory is implemented as Multiple Time Pro
