4.6
4.6.1
The PIC24FJ64GA1/GB0 families have Configuration
bits stored in the last three locations of implemented
program memory (see Table 2-2 for locations). These
bits can be set or cleared to select various device con-
figurations. 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.

Note:
Description
Although not implemented with a specific
function, the bit at CW1<15> must always
be maintained as ‘0’ to ensure device
functionality, regardless of the settings of
other Configuration bits.
