RF operations

219

During the RF write cycle Wt, there should be no modulation (neither 100% nor 10%),

otherwise the ST25DVxxx may not program correctly the data into the Configuration byte.

The Wt time is equal to t1nom + N × 302 µs (N is an integer).

Request parameters:

•

Request flags

•

UID (optional)

Note:

Please refer to Table 8: System configuration memory map for details on register

addresses.

Response parameter:

•

No parameter. The response is sent back after the writing cycle.

Response parameter:

•

Error code as Error_flag is set:

–

02h: command not recognized

–

03h: command option is not supported

–

0Fh: error with no information given

–

10h: block not available

–

12h: block already locked, content can't change

–
