PIC16(L)F1508/9
The following features are associated with access and
control of program memory and data memory:
• PCL and PCLATH
• Stack
• Indirect Addressing
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).
