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 40

bytes of register locations, up to 512 bytes of RAM

and up to 16K bytes of user program memory. The

RAM space includes up to 128 bytes for the stack

from 0100h to 017Fh.

Figure 5. Memory Map

The highest address bytes contain the user reset

and interrupt vectors.

IMPORTANT: Memory locations noted “Re-

served” must never be accessed. Accessing a re-

served area can have unpredictable effects on the

device.
