1.3 REGISTER & MEMORY MAP

As shown in the Figure 3, the MCU is capable of

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

ters.

The available memory locations consist of 128

bytes of register location, up to 2Kbytes of RAM,

up to 256 bytes of data EEPROM and up to

Figure 3. Memory Map

60Kbytes 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.
