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).
