8 / 40 page PIC16F/LF182X/PIC12F/LF1822 DS41390C-page 8 Advance Information 2010 Microchip Technology Inc. 3.1 User ID Location A user may store identification information (user ID) in four designated locations. The user ID locations are mapped to 8000h-8003h. Each location is 14 bits in length. Code protection has no effect on these memory locations. Each location may be read with code protection enabled or disabled. 3.2 Device ID The device ID word is located at 8006h. This location is read-only and cannot be erased or modified. Note: MPLAB® IDE only displays the 7 Least Significant bits (LSb) of each user ID location, the upper bits are not read. It is recommended that only the 7 LSb’s be used if MPLAB IDE is the primary tool used to read these addresses. REGISTER 3-1: DEVICE ID: DEVICE ID REGISTER(1) R RRRR RR DEV8 DEV7 DEV6 DEV5 DEV4 DEV3 DEV2 bit 13 bit 7 R RRRR RR DEV1 DEV0 REV4 REV3 REV2 REV1 REV0 bit 6 bit 0 Legend: P = Programmable bit U = Unimplemented bit, read as ‘0’ R = Readable bit W = Writable bit ‘0’ = Bit is cleared -n = Value at POR ‘1’ = Bit is set x = Bit is unknown bit 13-5 DEV<8:0>: Device ID bits These bits are used to identify the part number. bit 4-0 REV<4:0>: Revision ID bits These bits are used to identify the revision. Note 1: This location cannot be written. |
