14.15 In-Circuit Debugger
When the DEBUG bit in the configuration word is pro-
grammed to a ‘0’, the in-circuit debugger functionality is
enabled. This function allows simple debugging
functions when used with MPLAB
microcontroller has this feature enabled, some of the
resources are not available for general use. Table 14-8
shows
background debugger.
TABLE 14-8:
To use the in-circuit debugger function of the microcon-
troller, the design must implement In-Circuit Serial Pro-
gramming connections to MCLR/V
and RB6. This will interface to the in-circuit debugger
module available from Microchip or one of the third
party development tool companies.

14.16 Program Verification/Code
If
programmed, the on-chip program memory can be
read out for verification purposes.
14.17 ID Locations
Four memory locations (2000h-2003h) are designated
as ID locations, where the user can store checksum or
other code identification numbers. These locations are
not accessible during normal execution but are
readable and writable during program/verify. It is
recommended that only the 4 Least Significant bits of
the ID location are used.
