Configuration memory organization
The EMDCB configuration memory is divided into the following areas:
◼
Public data
◼
Protected data
In addition to that, EMDCB maintains a private configuration memory region used to store
default parameters and confidential information which is not accessible to the user. The
following chapters provide information on key settings available via NFC.
The smallest access unit is one page of 4 byte. If less than a full page (i.e. less than 4
byte) shall be written to NFC memory then the whole page should be read, its content be
modified as needed and the result be written back.

Note that a read access to page
0xE5

out the current PIN code.
