Read Multiple Blocks
The Read Multiple Blocks command allows for retriev-
ing the data of up to three memory blocks. This com-
mand uses two command-specific parameters, which
are the starting block number and the number of blocks
to read. Valid starting block numbers are 00h to 11h.
Permissible number of block values are 0, 1, and 2,
corresponding to 1, 2, and 3 blocks. A request that
attempts reading beyond block number 11h generates
a response with error code 10h. If the Option_flag bit is
set, the response includes the block’s security status.
The security status codes are the same when reading
single blocks. See the
Read Single Block section for
more details.
Custom Read Block
The Custom Read Block command allows for retrieving
the data of a single memory block. This command uses
one command-specific parameter, which is the memory
block number. Valid block numbers are 00h to 11h. If
the Option_flag bit is set, the response includes the
block’s security status. The security status codes are
the same as when reading single blocks. See the
Read
Single Block section for more details.
