75 / 100 page  LRIS64K Commands codes Doc ID 15336 Rev 11 75/100 24.13 Get Multiple Block Security Status When receiving the Get Multiple Block Security Status command, the LRIS64K sends back the sector security status. The blocks are numbered from '00h to '07FFh' in the request and the value is minus one (–1) in the field. For example, a value of '06' in the “Number of blocks” field requests to return the security status of 7 blocks. The Protocol_extention_flag should be set to 1 for the LRIS64K to operate correctly. If the Protocol_extention_flag is at 0, the LRIS64K answers with an error code. During the LRIS64K response, if the internal block address counter reaches 07FFh, it rolls over to 0000h and the Sector Security Status bytes for that location are sent back to the reader. Request parameter: ● UID (optional) ● First block number ● Number of blocks Response parameters: ● Sector security status (see Table 65: Sector security status) Table 63. Get Multiple Block Security Status request format Request SOF Request _flags Get Multiple Block Security Status UID(1) 1. Gray means that the field is optional.
