Card State Transition Table
Although the MultiMedia protocol state machine is not abserved, the command sequence sent from host must follow
the state transition table as below.

When the card finishes the read operation (CMD9, CMD10, CMD17) the state is changed from data state to ready
state, automatically.
7.6.2 Responses
There are several types of response tokens. As in the MultiMediaCard mode, all are transmitted
MSB first:
Format R1
This response token is sent by the card after every command, with the exception of SEND_STATUS commands. It
is one byte long, and the MSB is always set to zero. The other bits are error indica-tions, an error being signaled by
a '1'. The structure of the R1 format is given in Figure 48. The meaning of the flags is defined as follows:
In idle state: The card is in idle state and running the initializing process.
Erase reset: An erase sequence was cleared before executing because an out of erase sequence command was
received.
Illegal command: An illegal command code was detected.
Communication CRC error: The CRC check of the last command failed.
Erase sequence error: An error occurred in the sequence of erase commands.
Address error:A misaligned address, which did not match the block length, was used in the command.
Parameter error: The command's argument (e.g. address, block length) was out of the allowed range for this card.
