Block-Oriented Read Commands (class 2)
CMD
index Type Argument

CMD16 ac [31:0] block
R1
length
SET_BLOCKLEN
Selects a block length (in bytes) for all
following block-oriented read
commands and lock card command.*1
CMD17 adtc [31:0] data
R1
READ_SINGLE_BL Reads a block of the size selected by
address
OCK
the SET_BLOCKLEN command.*2
CMD18 adtc [31:0] data
R1
READ_MULTIPLE_ Continuously send blocks of data until
address
BLOCK
interrupted by a stop.
Notes: 1. The default block length is as specified in the CSD. These Hitachi MultiMediaCards do not
support partial block write, so the write block size defined by WRITE_BLK_LEN is parmanently
assigned to the value 512 bytes.
2. The data transferred must not cross a physical block boundary unless READ_BLK_MISALIGN is
set in the CSD. These Hitachi MultiMediaCards do not support read block operations with
boundary crossing (READ_BLK_MISALIGN = ‘0’), so the data transferred must not cross a
physical block boundary.
