3 REGISTER & MEMORY MAP
As shown in Figure 5, 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, up to 1024 bytes of
RAM and up to 32 Kbytes of user program memo-
ry. The RAM space includes up to 256 bytes for
the stack from 0100h to 01FFh.
Figure 5. Memory Map
The highest address bytes contain the user reset
and interrupt vectors.
IMPORTANT: Memory locations marked as “Re-
served” must never be accessed. Accessing a re-
served area can have unpredictable effects on the
device.
