5.0
The PIC18F8410/8490/8493 family devices have
several Configuration Words. These bits can be set or
cleared to select various device configurations. All
other memory areas should be programmed and
verified prior to setting Configuration Words. These bits
may be read out normally, even after read or
code-protected. Table 5-2 and Table 5-3 provide
information on various configuration bits.
5.1
A user may store identification information (ID) in eight
ID locations mapped in 200000h:200007h. It is
recommended that the Most Significant nibble of each

5.2
The device ID word for the PIC18F8410/8490/8493
family is located at 3FFFFEh:3FFFFFh. These bits may
be used by the programmer to identify what device type
is being programmed and read out normally, even after
code or read-protected.
