Command sequences are controlled by the sequencers on both the MMCIF side and the MMC
card side. Normally, these operate synchronously. However, if an error occurs or a command is
aborted, these may become temporarily unsynchronized. Be careful when setting the CMDOFF bit
in OPCR, issuing the CMD12 command, or processing an error in MMC mode. A new command
sequence should be started only after the end of the command sequence on both the MMCIF and
card sides is confirmed.
