3 REGISTER AND MEMORY MAP
As shown in
64 Kbytes 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
ure
Figure 3. Memory Map
Notes:
1. DEE0h, DEE1h, DEE2h and DEE3h addresses are located in a reserved area but are special bytes containing also the
RC calibration values which are read-accessible only in user mode. If all the EEPROM data or Flash space (including the
RC calibration values locations) has been erased (after the readout protection removal), then the RC calibration values
can still be obtained through these four addresses.

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.
