Note 1: XT, HS or LP Oscillator mode assumed.
= 1024 T
(drawing not to scale). This delay will not be there for RC Oscillator mode.
3: GIE = 1 assumed. In this case, after wake- up, the processor jumps to the interrupt routine.
If GIE = 0, execution will continue in-line.
4: CLKO is not available in these oscillator modes but shown here for timing reference.
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
Address 0000h must be NOP
Last 100h words
0x070 (0x0F0, 0x170, 0x1F0)
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.

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.
