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 locations, 256 bytes of RAM, 128
bytes of data EEPROM and up to 4 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

are located in Sector 0 (F000h-FFFFh).
The size of Flash Sector 0 and other device op-
tions are configurable by Option byte (refer to

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