As shown in Figure 4 and Figure 5: Memory map and sector address on page 34, the MCU is capable of

addressing 64 Kbytes of memories and I/O registers.

The available memory locations consist of 128 bytes of register locations, up to 1 Kbytes of RAM and up

to 32 Kbytes of user program memory. The RAM space includes up to 256 bytes for the stack from 0100h

to 01FFh.

The highest address bytes contain the user reset and interrupt vectors.

Caution:

Memory locations marked as ‘reserved’ must never be accessed. Accessing a reserved

area can have unpredictable effects on the device.
