MEMORY ORGANIZATION
There are three types of memory in PIC12(L)F1840
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)
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 PIC12(L)F1840 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).
Note 1:
The Data EEPROM Memory and the
method to access Flash memory through
the EECON registers is described in
.
