dsPIC33EVXXXGM00X/10X FAMILY

3.5 Programmer’s Model

The programmer’s model for the dsPIC33EVXXXGM00X/

10X family is shown in Figure 3-2. All registers in the

programmer’s model are memory-mapped and can be

manipulated directly by instructions. Table 3-1 lists a

description of each register.

In addition to the registers contained in the programmer’s

model, the dsPIC33EVXXXGM00X/10X family devices

contain control registers for Modulo Addressing and Bit-

Reversed Addressing, and interrupts. These registers

are described in subsequent sections of this document.

All registers associated with the programmer’s model

are memory-mapped, as shown in Table 4-1.
