The upper nine bits hold the Device ID. The lower five bits hold the Revision ID. See Section 11.5 “User ID, Device ID and Configuration Word Access” for more information on accessing these memory locations. Development tools, such as device programmers and debuggers, may be used to read the Device ID and Revision ID. 4.7 Register Definitions: Device ID REGISTER 4-3: DEVICEID: DEVICE ID REGISTER RRRRRR DEV<8:3> bit 13 bit 8 RRRRRRRR DEV<2:0> REV<4:0> bit 7 bit 0 Legend: R = Readable bit ‘1’ = Bit is set ‘0’ = Bit is cleared -n = Value when blank or after Bulk Erase bit 13-5 DEV<8:0>: Device ID bits bit 4-0 REV<4:0>: Revision ID bits These bits are used to identify the revision (see Table under DEV<8:0> above).
