PIC18F87J90 FAMILY
5.1.1
All PIC18 devices have a total of three hard-coded
return vectors in their program memory space. The
Reset vector address is the default value to which the
program counter returns on all device Resets; it is
located at 0000h.
PIC18 devices also have two interrupt vector
addresses for the handling of high-priority and
low-priority interrupts. The high-priority interrupt vector
is located at 0008h and the low-priority interrupt vector
is at 0018h. Their locations in relation to the program
memory map are shown in Figure 5-2.

Preliminary
5.1.2
Because PIC18F87J90 family devices do not have per-
sistent configuration memory, the top four words of
on-chip program memory are reserved for configuration
information. On Reset, the configuration information is
copied into the Configuration registers.
The Configuration Words are stored in their program
memory location in numerical order, starting with the
lower byte of CONFIG1 at the lowest address and end-
ing with the upper byte of CONFIG4. For these devices,
only
CONFIG3, are used; CONFIG4 is reserved. The actual
addresses of the Flash Configuration Word for devices
in the PIC18F87J90 family are shown in Table 5-1.
Their location in the memory map is shown with the
other memory vectors in Figure 5-2.
Additional details on the device Configuration Words
are provided in Section 24.1 “Configuration Bits”.
