CRC7 checksum (CRC)
Not used, always “1”
*The CRC checksum is computed by using the following formula:
CRC Calculation: G(x)=x
M(x)=(MID-MSB)*x
CRC[6…0]=Remainder[(M(x)*x
The Card Specific Data (CSD) Register configuration information is required to access

revision number. The “n” is the most significant nibble and the “m” is the least significant nibble. Example: the
PRV binary value filed for product revision (6.2) would be “01100010”.
The product revision is composed of two binary-coded decimal (BCD) digits (4 bits ea.) representing and “n.m”
