3 REGISTER & MEMORY MAP
As shown in
pable of addressing 64K bytes of memories and I/
O registers.
The available memory locations consist of up to
128 bytes of register locations, 128 bytes of RAM,
128 bytes of data EEPROM and up to 1.5 Kbytes
of user program memory. The RAM space in-
cludes up to 64 bytes for the stack from 0C0h to
0FFh.

The highest address bytes contain the user reset
and interrupt vectors.
The size of Flash Sector 0 is configurable by Op-
tion byte.
IMPORTANT: Memory locations marked as “Re-
served” must never be accessed. Accessing a re-
served area can have unpredictable effects on the
device.
