Command description

CMD24 adtc [31:0] data

R1

WRITE_BLOCK Write a block. The write-block-length

address

of the Hitachi MultiMediaCard is

permanently assigned to the value 512

bytes.*1

CMD25 adtc [31:0] data

R1

WRITE_MULTIPLE Continuously writes blocks of data until

address

a STOP_TRANSMISSION follows.

CMD26 adtc [31:0] stuff bits R1

PROGRAM_CID

Programming of the card identification

register. This command is only done

once per MultiMediaCard card. The

card has some hardware to prevent

this operation after the first

programming. Normally this command

is reserved for the manufacturer. The

CID register is programmed at the

manufacture.

CMD27 adtc [31:0] stuff bits R1

PROGRAM_CSD Programming of the programmable bits

of the CSD.

Note:

1. The data transferred must not cross a physical block boundary unless WRITE_BLK_MISALIGN

is set in the CSD. These Hitachi MultiMediaCards do not support write block operations with

bondary crossing (WRITE_BLK_MISALIGN = ‘0’), so the data transferred must not cross a

physical block boundary.
