3.0 MEMORY ORGANIZATION

There are three types of memory in PIC16(L)F1847:

Data Memory, Program Memory and Data EEPROM

Memory(1).

• Program Memory

• Data Memory

- Core Registers

- Special Function Registers

- General Purpose RAM

- Common RAM

- Device Memory Maps

- Special Function Registers Summary

• Data EEPROM memory(1)

Note 1: The Data EEPROM Memory and the

method to access Flash memory through

the EECON registers is described in

Section 11.0 “Data EEPROM and Flash

Program Memory Control”.

PIC16(L)F1847

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)F1847 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).
