PIC16(L)F1454/5/9

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 a 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).
