• 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”.

PIC12(L)F1840

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).
