5.15 NFC Tag Functions

5.15.1 Summary

Some module with NFC target function could be set to NFC Tag mode. It could be operated

by NFC Tag readers after set. The commands for target are command to operate NFC Tag

FLASH space over communication port. The commands for initiator are command to operate

NFC Tag FLASH space over RF interface.

The data storage space is 128 bytes. Organization is 4bytes/page * 32 pages. The page 0 and

page 1 are read only. First byte and second byte in page 2 are read only too.

5.15.2 Initiator Commands

5.15.2.1 Read Data from NFC Tag

Function: initiator (reader) read data from NFC Tag over RF interface. The NFC Tag

responds to the READ command by sending 16 bytes starting from the page address defined in

the command (e.g. if address is ‘03h‘ pages 03h, 04h, 05h, 06h are returned). If address is ‘1Fh’,

the contents of pages 1Fh, 00h, 01h and 02h are returned).

Host sends:

Frame 0xC8 PAGE Checksum

PAGE: 1 byte start page number, 0x00 to 0x1F

Success:

Frame 0xC8 DATA Checksum

DATA: 16 bytes data from NFC Tag

Failure:

Frame 0x37 Checksum

Example:

Send: 0x00 05 00 C8 07 CA

Return: 0x00 14 01 C8 07 07 07 07 08 08 08 08 FF FF FF FF FF FF FF FF DD

5.15.2.2 Write Data to NFC Tag

Function: A WRITE command is performed page-wise, programming 4 bytes in a page.

Host sends:

Frame 0xC9 PAGE DATA Checksum

PAGE: 1 byte page number

DATA: 4 bytes data to write

Success:

Frame 0xC9 Checksum

DATA: returned message from target

Failure:

Frame 0x36 Checksum

Example:
