Mainstream contactless smart card IC
9.7.1
Access conditions
The access conditions for every data block and sector trailer are defined by 3 bits, which
are stored non-inverted and inverted in the sector trailer of the specified sector.
The access bits control the rights of memory access using the secret keys A and B. The
access conditions may be altered, provided one knows the relevant key and the current
access condition allows this operation.
Remark:
With each memory access the internal logic verifies the format of the access
conditions. If it detects a format violation the whole sector is irreversible blocked.
Remark:
In the following description the access bits are mentioned in the non-inverted
mode only.
The internal logic of the MF1S5009 ensures that the commands are executed only after
an authentication procedure or never.
