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).
