Fast Read Dynamic configuration response format when Error_flag is set Response SOF Response_flags Error code CRC16 Response EOF - 8 bits 8 bits 16 bits - Response parameter: • Error code as Error_flag is set: – 02h: command not recognized – 03h: command option not supported – 0Fh: error with no information given – 10h: block not available Figure 72. Fast Read Dynamic configuration frame exchange between VCD and ST25DVxxx SOF Fast Read Dynamic configuration request VCD ST25DVxxx EOF t1 SOF Fast Read Dynamic configuration request EOF 7.6.44 Fast Write Dynamic Configuration On receiving the Fast Write Dynamic Configuration command, the ST25DV updates the Dynamic register addressed by the pointer. The Option_flag is not supported. The Inventory_flag must be set to 0. The data rate of the response is multiplied by 2 compared to Write Dynamic Configuration command. Table 238.
