LRIS2K

Read Single Block

57/102

Read Single Block

On receiving the Read Single Block command, the LRIS2K reads the requested block and

sends back its 32 bits value in the request. The Option_flag is supported.

Request parameters:

●

Option_flag

●

UID (optional)

●

Block number

Response parameters:

●

Block Locking Status if Option_flag is set (see Table 33: Block Locking status)

●

4 bytes of block data

Response parameter:

●

Error code as Error_flag is set

–

0Fh: other error

–

10h: block address not available
