There are several types of response tokens and all are transmitted MSB first.
The card sends this response token after every command with the exception of
SEND_STATUS commands. It is one-byte long, the MSB is always set to zero, and the
other bits are error indications (1= error).
The structure of the R1 format is shown in Figure 5-13 and the error definitions are listed
in Table 5-6.

Argument
R1 Response Format
R1 Response
The card is in an idle state and running initializing process.
An erase sequence was cleared before execution because an out-of-
erase sequence command was received.
An illegal command code was detected.
The CRC check of the last command failed.
An error in the sequence of erase commands occurred.
A misaligned address that did not match the block length was used in
the command.
The command’s argument (e.g., address, block length) was out of the
allowed range for this card.
