5.2 NFC memory map

The NFC memory is organized in pages (smallest addressable unit) where each page contains

4 byte of data. Several pages with similar functionality form an NFC memory area. PTM 535BZ

uses the following areas:

 Device Identification NDEF string (Read access only)

This area contains an NDEF string identifying key device parameters

 User Information NDEF string (Read / write access; no PIN required)

This area allows any user to read or write information about the device such as the

intended installation location or additional instructions

 NFC HEADER (Read access only)

This area contains information about the NFC revision

 ACTIVE CONFIGURATION (Read access only)

This area contains the currently used configuration

 NEW CONFIGURATION (Write access, PIN required to execute the update)

This area is used to change configuration values.
