The following features are associated with access and
control of program memory and data memory:
• PCL and PCLATH
• Stack
• Indirect Addressing
3.1
The enhanced mid-range core has a 15-bit program
counter capable of addressing 32K x 14 program
memory space.
implemented
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
