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.

The highest address bytes contain the user reset

and interrupt vectors.
