AcknowledgeAn acknowledge must be sent at the end of one data byte. The acknowledge-related clock pulse is generated by the master. The transmitter of data, either master or slave, releases the SDA line (HIGH) during the acknowledge clock pulse. The receiver pulls down the SDA line during the acknowledge clock pulse so that it remains stable LOW during the HIGH period of this clock pulse. The master can then generate either a STOP (P) condition to stop the transfer or a repeated START (Sr) condition to start a new transfer. A master-receiver indicates the end of data to the slave-transmitter by not generating an acknowledge on the last byte that was clocked out by the slave. The slave-transmitter releases the data line to allow the master to generate a STOP (P) or repeated START (Sr) condition.Acknowledge on the I2C-busData transfer on the I2C-busRegister read access To read out data from a specific register address in the Module, the host controller must use the following procedure: • Firstly, a write access to the specific register address must be performed as indicated
in the frame that follows • The first byte of a frame indicates the device address according to the I2C-bus rules • The second byte indicates the register address. No data bytes are added • The Read/Write bit is 0 After the write access, read access can start. The host sends the device address of the PN512. In response, the Module sends the content of the read access register. In one frame all data bytes can be read from the same register address. This enables fast FIFO buffer access or register polling. The Read/Write (R/W) bit is set to logic 1. Register read and write access I2C-bus timing
