• DSR_IMP
Defines if the configurable driver stage option is integrated on the card or not. If implemented a driver
stage register (DSR) must be implemented also.

These Hitachi MultiMediaCards' output drivers are not configurable. The parameter DSR_IMP is
permanently assigned to the value ‘0’.
• C_SIZE
This parameter is used to compute the card capacity. The card capacity is computed from the entries
C_SIZE, C_SIZE_MULT and READ_BLK_LEN as follows:
memory capacity = BLOCKNR*BLOCK_LEN
Where
BLOCKNR = (C_SIZE+1)*MULT
MULT = 2C_SIZE_MULT+2 (C_SIZE_MULT < 8)
BLOCK_LEN = 2 , READ_BLK_LEN (READ_BLK_LEN < 12)
Therefore, the maximal capacity which can be coded is 4096*512*2048 = 4 GBytes.
The following table shows the card capacity for each model.
