PIC16(L)F1526/27

3.0 MEMORY ORGANIZATION

These devices contain the following types of memory:

• Program Memory

- Configuration Words

- Device ID

- User ID

- Flash Program Memory

• Data Memory

- Core Registers

- Special Function Registers

- General Purpose RAM

- Common RAM

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 for the PIC16(L)F1526/27 family.

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).
