PIC18F2XJXX/4XJXX FAMILY
5.0
The Configuration Words of the PIC18F2XJXX/4XJXX
family devices are implemented as volatile memory
registers. All of the Configuration registers (CONFIG1L,
CONFIG1H,
CONFIG3H,
automatically loaded following each device Reset.
The data for these registers is taken from the four Flash
Configuration Words located at the end of program
memory. Configuration data is stored in order, starting
with CONFIG1L in the lowest Flash address and
ending with CONFIG4H in the highest. The mapping to
specific Configuration Words is shown in Table 5-1.
Users should always reserve these locations for
Configuration Word data and write their application
code accordingly.
The upper four bits of each Flash Configuration Word
should always be stored in program memory as ‘1111’.
This is done so these program memory addresses will
always be ‘1111 xxxx xxxx xxxx’ and interpreted
as a NOP instruction if they were ever to be executed.
Because the corresponding bits in the Configuration
registers are unimplemented, they will not change the
device’s configuration.
The Configuration and Device ID registers are
summarized in Table 5-2. A listing of the individual
Configuration bits and their options is provided in
Table 5-3.

CONFIGURATION WORD
- = unimplemented. Shaded cells are unimplemented, read as ‘0’.
The value of these bits in program memory should always be ‘1’. This ensures that the location is executed as a NOP if
it is accidentally executed.
This bit should always be maintained at ‘0’.
DEVID registers are read-only and cannot be programmed by the user.
