It is a 128 bit wide register, one-time programmable by the provider. It was programmed at the manufacturer. The CID is divided into eight slices: CID Fields Name Field Width CID-slice Note Manufacturer ID MID 8 [127:120] 1 OEM/Application ID OID 16 [119:104] Product name PNM 48 [103:56] Product revision PRV 8 [55:48] Product serial number PSN 32 [47:16] Manufacturing date MDT 8 [15:8] 7-bit CRC checksum CRC7 7 [7:1] Not used, always 1 1 [0:0] Note: 1. The value of MID is 0x06. The CID has to be error free. To ensure the correctness of the CID, a 7-bit CRC checksum is added to the end of the CID. The CRC7 is computed according to chapter “Cyclic Redundancy Check (CRC)”. Relative Card Address (RCA) The 16-bit relative card address register carries the card address assigned by the host during the card identification. This address is used for the addressed host to card communication after the card identification procedure. The default value of the RCA register is 0x0001. The value 0x0000 is reserved to set all cards in Standby State with the command SELECT_DESELECT_CARD (CMD7). The RCA is programmed with the command SET_RELATIVE_ADDRESS (CMD3) during the initialization procedure. The content of this register is lost after power down. The default value is assigned when an internal reset is applied by the power up detection unit of these Renesas MultiMediaCards, or when the command GO_IDLE_STATE (CMD0) is detected by these Renesas MultiMediaCards. |
