Page Write Saved even after failure code

When using a CLRC663 to write to an Ultralight EV1 Chip, on occasion I get back error code 0x0201

 

        status = phalMful_Write( pDataParams, Address, Data);

 

In these cases, I assume I have lost connection with the chip AND that my write is not saved.

 

However I find that often the write is successful, even though I get back an error status.

 

How do I interpret status = 0x0201?

 

Does it mean:

1) Write failed (doubt it)

2) Write maybe failed, but can't be sure (seems like it)

3) Write succeeded, then connection lost (can it be guaranteed?)

4) Write status impossible to determine without reconnection
