3.1

Program Memory Organization

The enhanced mid-range core has a 15-bit program

counter capable of addressing a 32K x 14 program

memory space. Table 3-1 shows the memory sizes

implemented for these devices. Accessing a location

above these boundaries will cause a wrap-around within

the implemented memory space. The Reset vector is at

0000h and the interrupt vector is at 0004h (see

Figure 3-1 and Figure 3-2).
