3 REGISTER & MEMORY MAP
As shown in
dressing 64K bytes of memories and I/O registers.
The available memory locations consist of 128
bytes of register location, 256 bytes of RAM and
up to 8 Kbytes of user program memory. The RAM
space includes up to 128 bytes for the stack from
0100h to 017Fh.
The highest address bytes contain the user reset
and interrupt vectors.
The Flash memory contains two sectors (see

IMPORTANT: Memory locations marked as “Re-
served” must never be accessed. Accessing a re-
seved area can have unpredictable effects on the
device.
