SLAVE agreement description The agreement format is the same with IIC: Control command format STARTÆ55H+ACKÆCOMMAND+ACKÆSTOP; State information format STARTÆAAH+ACKÆDATA1+ACK+……+DATAn+ACKÆSTOP; Agreement description ACK format: The host will set DATA bus high at the falling edge of CLK, and judge the state of DATA bus at the rising edge of CLK. Then it will set DATA low if its state is high and exit if its state is low. Data format: Sending interval of the control command is longer than 30ms; State information must be received continuously with interval time longer than 50ms.
