4.1 Program Memory Address Map
The dsPIC30F devices have a 4M x 24-bit program memory address space, shown in Figure 4-1.
There are three available methods for accessing program space.
1. Via the 23-bit PC.
2. Via table read (TBLRD) and table write (TBLWT) instructions.
3. By mapping a 32-Kbyte segment of program memory into the data memory address
space.
The program memory map is divided into the user program space and the user configuration
space. The user program space contains the Reset vector, interrupt vector tables, program
memory and data EEPROM memory. The user configuration space contains non-volatile
configuration bits for setting device options and the device ID locations.
