16.5.6.1. STOP_TRANSMISSION (CMD12)

The host can send the STOP_TRANSMISSION (CMD12) command on the CMD pin at any time while a data transfer is in progress. Perform the following steps to send the STOP_TRANSMISSION command to the SD/SDIO card device:
  1. Set the wait_prvdata_complete bit of the cmd register to 0.
  2. Set the stop_abort_cmd in the cmd register to 1, which ensures that the CIU stops.

The STOP_TRANSMISSION command is a non‑data transfer command.
