Every individual Read/Write (RW) card shall have a unique identification number. The structure of the CID register is defined in the following paragraphs:
Name | Field | Width | CID-slice |
Manufacturer ID | MID | 8 | [127:120] |
OEM/Application ID | OID | 16 | [119:104] |
Product name | PNM | 40 | [103:64] |
Product revision | PRV | 8 | [63:56] |
Product serial number | PSN | 32 | [55:24] |
Reserved | -- | 4 | [23:20] |
Manufacturing date | MDT | 12 | [19:8] |
CRC7 checksum | CRC | 7 | [7:1] |
Not used, always 1 | - | 1 | [0:0] |
