59 / 66 page MultiMediaCard TM 59 Data Response Every data block written to the card will be acknowledged by a data response token. It is one byte long and has the following format: Figure 4-11 Data Response The meaning of the status bits is defined as follows: ‘010’ - Data accepted ‘101’ - Data rejected due to a CRC error. ‘110’ - Data rejected due to a Write Error. 4.10.13 Data Tokens Read and write commands have data transfers associated with them. Data is being transmitted or received via data tokens. All data bytes are transmitted MSB first. Data tokens are 4 to (N + 3) bytes long (Where N is the data block length set using the SET_BLOCK_LENGTH Command) and have the following format : - First byte: Start Byte Token Type Transaction Type 7 Bit Position 0 Start Block Single Block Read 1 1 1 1 1 1 1 0 Start Block Multiple Block Read 1 1 1 1 1 1 1 0 Start Block Single Block Write 1 1 1 1 1 1 1 0 Start Block Multiple Block Write 1 1 1 1 1 1 0 0 Stop Tran Multiple Block Write 1 1 1 1 1 1 0 1 Figure 4-12 Data Tokens - Bytes 2 – (N + 1) : User data - Last two bytes: 16 bit CRC. 4.10.14 Data Error Token If a read operation fails and the card cannot provide the required data, it will send a data error token instead. This token is one byte long and has the following format: |
