Stream read
There is a stream oriented data transfer controlled by READ_DAT_UNTIL_STOP (CMD11). This command instructs
the card to send its payload, starting at a specified address, until the host sends a STOP_TRANSMISSION command
(CMD12). Please note that the host stop command has an execution delay due to the serial command transmission.
The data transfer stops after the end bit of the next command with interrupt ability.
If the end of the memory range is reached while sending data and no stop command has yet been sent by the host,
the data transfer will continued. The data sent than is undefined. The host has to observe the boundaries of the memory
range.
Block read
Block read is similar to stream read, except the basic unit of data transfer is a block whose maxi-mum size is defined
in the CSD (READ_BLK_LEN). READ_BLK_PARTIAL is set, thus smaller blocks whose starting and ending address
are wholly contained within one physical block (as defined by READ_BLK_LEN) may also be transmitted. Unlike
stream read, a CRC is appended to the end of each block ensuring data transfer integrity. READ_SINGLE_BLOCK
(CMD17) starts a block read and after a complete transfer the card goes back to Transfer State.
CMD18 (READ_MULTIPLE_BLOCK) starts a transfer of several consecutive blocks. Two types of multiple block read
transactions are defined (the host can use either one at any time):
Open-ended Multiple block read
The number of blocks for the read multiple block operation is not defined. The card will continuously transfer data
blocks until a stop transmission command is received.
Multiple block read with pre-defined block count
The card will transfer the requested number of data blocks, terminate the transaction and return to transfer state.
Stop command is not required at the end of this type of multiple block read, unless terminated with an error. In order
to start a multiple block read with pre-defined block count the host must use the SET_BLOCK_COUNT command
(CMD23) immediately preceding the READ_MULTIPLE_BLOCK (CMD18) command. Otherwise the card will start
an open-ended multiple block read which can be stopped using the STOP_TRANSMISION command.
The host can abort reading at any time, within a multiple block operation, regardless of the its type. Transaction abort
is done by sending the stop transmission command.
If the card detects an error (e.g. out of range, internal error, etc.) during a multiple block read operation (both types)
it will stop data transmission and remain in the Data State. The host must than abort the operation by sending the stop
transmission command. The read error is reported in the response to the stop transmission command.
If the host sends a stop transmission command after the card transmits the last block of a multiple block operation
with a pre-defined number of blocks, it will be responded to as an illegal command, since the card is no longer in data
state.
