DB-SIZE: 

Number of bytes of one data block.  

 

DB: 

Data of the data block to be written to the Transponder. The required block size is defined 
by DB-SIZE. The number of the expected bytes are DB-N * DB-SIZE. 

 

DB-ADR-E: 

Block number were the error occurred.  

 

NOTE: 

If an error occurred during a write command, the number of the block were the error oc-
curred will be send to host
