The following features are associated with access and
control of program memory and data memory:
• PCL and PCLATH
• Stack
• Indirect Addressing

implemented for the PIC16(L)F1938/9 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).
