Functional Example for the MMC/SD Module
MOTOROLA
Multimedia Card/Secure Digital Host Controller Module (MMC/SD)
20-61
20.7.8.5.2 R1b—Normal Response with Busy
•
Identical to R1 with an optional busy signal transmitted on the data line
•
Card can become busy after receiving these commands based on its state prior to the command
reception. The MMC/SD module must check for busy at the response.
20.7.8.5.3 R2—CID, CSD Register
•
Response length is 136 bits
•
CID contents sent as response to
ALL_SEND_CID
(CMD 2) and
SEND_CID
(CMD10)
•
CSD contents sent as response to
SEND_CSD
(CMD9)
•
Only the bits [127…1] of the CID and CSD are transferred (the reserved bit [0] of these registers is
replaced by the end bit of the response)
20.7.8.5.4 R3—OCR Register
•
Response length is 48 bits
•
OCR contents sent as response to
SEND_OP_COND
(CMD1, MMC) or
SD_APP_OP_COND
(ACMD41, SD)
20.7.8.5.5 R4—Fast I/O for MMC Only
•
Response length is 48 bits
•
Argument field contains the RCA of the addressed card, the register address to be read-out or
written-to, and the registers’ contents
