Description
Used either to transfer a data
block to the card or to get a
data block from the card for
general purpose / application
specific commands. The size
of the data block is set by the
SET_BLOCK_LEN
command.
RW_MULTIPLE_REGI
STER
CE-ATA devices contain a
set of Status and Control
registers that begin at register
offset 80h.These registers
are used to control the
behavior of the device and to
retrieve status information
regarding the operation of the
device. All Status and Control
registers are WORD (32-bit)
in size and are WORD
aligned. CMD60 shall be
used to read and write these
registers.
RW_MULTIPLE_BLOC The host issues a
K
RW_MULTIPLE_BLOCK
(CMD61) to begin the data
transfer for the ATA
command.
SET_BUS_WIDTH
Defines the data bus width
('00'=1bit or '10'=4bit bus) to
be used for data transfer. The
allowed data bus widths are
given in SCR register.
SD_STATUS
Send the SD memory card
status.
SEND_NUM_WR_SEC Send the number of the
TORS
written sectors (without
errors). Responds with 32-bit
plus the CRC data block.
SET_WR_BLK_ERAS -
E_COUNT
SD_APP_OP_COND
Asks the accessed card to
send its operating condition
register (OCR) contents in
the response on the CMD
line.
SET_CLR_CARD_DET -
