3 REGISTER & MEMORY MAP

As shown in the Figure 7, the MCU is capable of

addressing 64K bytes of memories and I/O regis-

ters.

The available memory locations consist of 64

bytes of register locations, 768 bytes of RAM and

up to 16 Kbytes of user program memory. The

RAM space includes up to 128 bytes for the stack

from 0100h to 017Fh.

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-

seved area can have unpredictable effects on the

device.
