MCP19116/7

11.0 MEMORY ORGANIZATION

There are two types of memory in the MCP19116/7:

• Program Memory

• Data Memory

- Special Function Registers (SFRs)

- General Purpose RAM

11.1

Program Memory Organization

The MCP19116/7 devices have a 13-bit program

counter capable of addressing an 8000 x 14 program

memory space. The Reset vector is at 0000h and the

Interrupt vector is at 0004h (refer to Figure 11-1). The

width of the program memory bus (instruction word) is

14 bits. Since all instructions are a single word, the

MCP19116/7 devices have space for 8000 instructions.
