SectorAddress
0 to 16,777,215 depending on the capacity of the card. Each sector is 512
bytes in size. There are 2048 sectors per every 1Mb of card memory.
data
bytes long. Unused bytes must be padded even if not all are used.
Description :
and other commands for storage that can be retrieved and used later on. It can
also be used as general purpose storage for user specific data. Downloads
must always be limited to 512 bytes in length. For large objects such as
images, the data must be broken up into multiple sectors (chunks of 512 bytes)
and this command then maybe used many times until all of the data is written
into the card. If the data block to be written is less than 512 bytes in length,
then make sure the rest of the remaining data are padded with 00hex or FFhex
(it can be anything).
If only few bytes of data are to be written then the Write Byte command can be
used.
Once this command message is sent, the
write the data into its memory card and at the end of which it will reply back with
an ACK(06hex) if the write cycle was successful. If there was a problem in
writing the data to the card a NAK(15hex) will be sent back without any write
attempts.
Only data
message such as Sector Address are not stored.
