GEN_CND
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 shall be set by

Turns the CRC option on or off. A
‘
1
’

option on, a
‘
0
’

Notes: 1. The default block length is as specified in the CSD.
2. The data transferred must not cross a physical block boundary unless READ_BLK_MISALIGN is
set in the CSD.
3. R1b: R1 response with an optional trailing busy signal.
4. The data transferred must not cross a physical block boundary unless WRITE_BLK_MISALIGN
is set in the CSD.
5. 32 write protection bits (representing 32 write protect groups starting at the specified address)
followed by 16 CRC bits are transferred in a payload format via the data line. The last (least
significant) bit of the protection bits corresponds to the first addressed group. If the addresses of
the last groups are outside the valid range, then the corresponding write protection bits shall be
set to zero.
6. ‘1’ the host gets a block of data from the card.
‘0’ the host sends block of data to the card.
No
