47 / 66 page MultiMediaCard TM 47 check did not fail) or not. In the case of transmission error the card sends a negative CRC status (“101” bin) which forces the host to retransmit the data. In the case of non-erroneous transmission the card sends a positive CRC status (“010” bin) and starts the data programming procedure. Timing of The block Write Command If the card does not have any more free data receive buffer, the card indicates it by pulling down the data line to LOW. The card stops pulling down the data line as soon as at least one receive buffer for the defined data transfer block length becomes free. This signaling does not give any information about the data write status. This information has to be polled by the status polling command. Erase block timing The host must first tag the sector to erase. The tagged sector(s) are erased in parallel by using the CMD35,36 CMD38. The card busy signaling is also used for the indication of the card erase procedure duration. In this case the end of the card busy signaling also does mean that the erase of all tagged sectors has been finished. The host can (also) request the card to send the actual card state using the CMD13. |
