Register and memory mapping
As shown in
registers.
The available memory locations consist of 128 bytes of register locations, 384 bytes of RAM
and 4 to 8 Kbytes of Flash program memory. The RAM space includes up to 128 bytes for
the stack from 180h to 1FFh.
The highest address bytes contain the user reset and interrupt vectors.
The Flash memory contains two sectors (see
addressing space so the reset and interrupt vectors are located in Sector 0 (FFE0h-FFFFh).
The size of Flash Sector 0 and other device options are configurable by option bytes (refer
to
Memory locations marked as “Reserved” must never be accessed. Accessing a reserved
area can have unpredictable effects on the device.
