MCP19111
11.0 MEMORY ORGANIZATION
There are two types of memory in the MCP19111:
• Program Memory
• Data Memory
- Special Function Registers (SFRs)
- General Purpose RAM
11.1 Program Memory Organization
The MCP19111 has a 13-bit program counter capable
of addressing an 8K x 14 program memory space. Only
the first 4K x 14 (0000h-0FFFh) is physically
implemented. Addressing a location above this
boundary will cause a wrap-around within the first
4K x 14 space. The Reset vector is at 0000h and the
interrupt vector is at 0004h (see Figure 11-1). The width
of the program memory bus (instruction word) is
14-bits. Since all instructions are a single word, the
MCP19111 has space for 4K of instructions.
