PIC24F16KL402 FAMILY
DS30001037C-page 182  2011-2013 Microchip Technology Inc.
23.3 Unique ID
A read-only Unique ID value is stored at addresses,
800802h through 800808h. This factory programmed
value is unique to each microcontroller produced in the
PIC24F16KL402 family. To access this region, use
Table Read instructions or Program Space Visibility.
To ensure a globally Unique ID across other Microchip
microcontroller families, the “Unique ID” value should
be further concatenated with the family and Device ID
values stored at address, FF0000h.
