Configuration Bits Programming
3.6.1
OVERVIEW
The dsPIC33F/PIC24H devices have Configuration
bits stored in twelve 8-bit Configuration registers,
aligned on even configuration memory address
boundaries. These bits can be set or cleared to select
various device configurations. There are three types of
Configuration bits: system operation bits, code-protect
bits and unit ID bits. The system operation bits
determine the power-on settings for system level
components, such as oscillator and Watchdog Timer.
The code-protect bits prevent program memory from
being read and written.
The register descriptions for the FBS, FSS, FGS,
FOSCSEL,
FOSC,
FWDT,
FPOR
and
FICD
Configuration registers are shown in Table 3-2.
Note 1: If any of the code-protect bits in FBS,
FSS or FGS is clear, the entire device
must be erased before it can be
reprogrammed.
