Reset to Ready

On receiving a Reset to Ready command, the ST25DVxxx returns to the Ready state if no error occurs. In the

Addressed mode, the ST25DVxxx answers an error code only if the UID is equal to its own UID. If not, no

response is generated.

The Option_flag is not supported, and the Inventory_flag must be set to 0.
