How to decode device ID returned from ICD-S
PostPosted: Wed Oct 19, 2005 4:59 am     Reply with quote
I have PIC18F2520 and ICD unit. I'd like to see what is silicon revision of PIC18F2520 from ICD Control Program V2.25/Advanced/Device ID. ICD returns: "PIC18 Device ID: 1101". I see from MicroChip document DS80229B.PDF ( PIC18F2420/2520/4420/4520 Data Sheet Errata ) that PIC18F2520 bits DEV2..DEV0 must be 000, bits REV4..REV0 contains device revision and bits DEV10..DEV3 must be 0001 0001.
I thing, that 11 is DEV10..DEV3 bits, and 01 is DEV2..DEV0 + REV4..REV0 bits, am I right ?
