* : Reserved for future use

The security status of the user area is stored in the block security status bit in system area blocks of “3EH”

and “3FH” per bit in each block. A user area is unlocked when the corresponding block security status bit is

“0”; it is locked (disable to write state) when the corresponding block security status bit is “1”. In the same

way, data in the security status of AFI and DSFID are stored in “AFI Lock Status” and “DSFID Lock Status”

respectively.

The EAS bit is 1 bit, and it is used for setting EAS status.

It is possible to read up to 64 blocks data by one command and to write up to 2 blocks data by one command.
