command class is supported.
•
The maximum read data block length is computed as 2
range 512...2048 bytes (see Chapter 4.11 for details). Note that in SD Memory Card the WRITE_BL_LEN is always
equal to READ_BL_LEN
•
Partial Block Read is always allowed in SD Memory Card. It means that smaller blocks can be used as well. The
minimum block size will be one byte.
•
Defines if the data block to be written by one command can be spread over more than one physical block of the memory
device. The size of the memory block is defined in WRITE_BL_LEN.
