Fast Read Single Block

On receiving the Fast Read Single Block command, the LRI2K reads the requested block

and sends back its 32-bit value in the response. The Option_flag is supported. The data rate

of the response is multiplied by 2.

Request parameters:

●

Option_flag

●

UID (Optional)

●

Block number

Response parameter:

●

Block Locking Status if Option_flag is set

●

4 bytes of Block Data

Response parameter:

●

Error code as Error_flag is set:

–

0Fh: other error

–

10h: block address not available
