3.0 MEMORY ORGANIZATION
There are three types of memory in PIC16(L)F1934/6/7
devices: 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)F1934/6/7
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 32K x 14 program
memory space. Table 3-1 shows the memory sizes
implemented for the PIC16(L)F1934/6/7 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 Figures 3-1 and 3-2).
