The card capacity is shown at “C_SIZE”.
The content of this register is a 5 bit binary coded value, used to calculate the size of the erasable unit of
these Renesas MultiMediaCards. The size of the erase unit (also referred to as erase group in chapter
“Memory Array Partitioning”) is determined by the ERASE_GRP_SIZE and the ERASE_GRP_MULT
entries of the CSD, using the following equation:
The parameter ERASE_GRP_SIZE is permanently assigned to the value ‘0’. The size of erasable unit for
these Renesas MultiMediaCards is (0+1) * (15+1) = 16, which means that the 8 KByte area can be erased
in a single erase group command (CMD35, CMD36 and CMD38).
