32.1 INTRODUCTION
At their highest level of functionality, PIC24F devices integrate several features that affect the
entire device as a whole. They add convenience and flexibility of design for the user, and allow
the devices to be incorporated into a wider range of designs. These include:
Flexible Configuration Options Allowing users to select a wide range of basic
microcontroller operating options and changing them if needed during run time.
Device Identification Allowing electronic confirmation of a device part number and
revision level in the target application.
On-Chip Voltage Regulator Allowing the device to be used over a range of application
voltage levels.
32.2 DEVICE CONFIGURATION
The basic behavior and operation of PIC24F devices are set by the device Configuration bits.
These allow the user to select a wide range of options and optimize the microcontrollers
operation to the applications requirements.
In all PIC24F family devices, device Configuration bits are mapped to the devices program
memory space, starting at location F80000h. This is beyond the user program memory space
and belongs to the configuration memory space (800000h-FFFFFFh).
The method by which the Configuration bits are programmed differs between major device
families. The details are discussed in Section 32.2.1 PIC24F J-Series Flash Devices and
Section 32.2.2 PIC24F K-Series Flash Devices.
Table 32-1 provides a list of the most common Configuration bit options. Note that this is not a
comprehensive list; certain device families will have unique configuration options that are specific
to its peripheral set. Each Configuration bit and its operation is described in the relevant section
of the PIC24F Family Reference Manual. For more information on Configuration bit mapping of
a particular device, refer to the specific device data sheet.
Note: All the bits that are described here are not available on all the devices.
