Lock DSFID

On receiving the Lock DSFID request, the ST25TV02K/512 lock the DSFID value permanently. When the

Option_flag is set, wait for EOF to respond.

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

ST25TV02K/512 may not lock correctly the DSFID value in memory. The Wt time is equal to t1nom + N × 302 µs

(N is an integer).
