User manual
5.3.5 Command format
The command path operates in a half-duplex mode, so that commands and responses
can either be sent or received. If the CPSM is not in the SEND state, the MCICMD output
is in HI-Z state, as shown in
MCICLK edge. All commands have a fixed length of 48 bits.
command format.
Table 482. Command format
The MCI adapter supports two response types. Both use CRC error checking:
Note: If the response does not contain CRC (CMD1 response), the device driver must
ignore the CRC failed status.
Table 483. Simple response format
Table 484. Long response format
The command register contains the command index (six bits sent to a card) and the
command type. These determine whether the command requires a response, and
whether the response is 48 or 136 bits long (see
(MCICommand - 0xE008 C00C)”

- 0xE008 C034)”
