• 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 Mobile Embedded Flashes' 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.
