3 REGISTER & MEMORY MAP
As shown in
Figure 3
, the MCU is capable of ad-
dressing 64K bytes of memories and I/O registers.
The available memory locations consist of 128
bytes of register locations, 384 bytes of RAM, 256
bytes of data EEPROM and 8 Kbytes of user pro-
gram 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
Fig-
ure 3
) mapped in the upper part of the ST7 ad-
dressing space so the reset and interrupt vectors
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
sec-
tion 15.1 on page 130
).
IMPORTANT:
Memory locations marked as “Re-
served” must never be accessed. Accessing a re-
seved area can have unpredictable effects on the
device.l
