3.1 Program Memory Organization
The enhanced mid-range core has a 15-bit program
counter capable of addressing 32K x 14 program
memory space. Table 3-1 shows the memory sizes
implemented. 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).
