NFC memory map
The EMDCB NFC configuration memory is divided into the following three areas:
◼
Public read-only data
◼
Private read / write data (PIN protected)
◼
Private read-only data (PIN protected)
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, modified as
needed and the result be written back.
The organization of the NFC configuration memory is shown in Table 5 below.
