    Datasheet - Detailed Description
    

    Bus Not Busy: Both data and clock lines remain HIGH.
    

    Start Data Transfer: A change in the state of the data line, from HIGH to LOW, while the clock is HIGH, defines a START condition.
    

    Stop Data Transfer: A change in the state of the data line, from LOW to HIGH, while the clock line is HIGH, defines the STOP condition.
    

    Data Valid: The state of the data line represents valid data when, after a START condition, the data line is stable for the duration of the HIGH 
    

    period of the clock signal. The data on the line must be changed during the LOW period of the clock signal. There is one clock pulse per bit of 
    

    data. Each data transfer is initiated with a START condition and terminated with a STOP condition. The number of data bytes transferred 
    

    between START and STOP conditions are not limited, and are determined by the master device. The information is transferred byte-wise and 
    

    each receiver acknowledges with a ninth bit.
    

    Acknowledge: Each receiving device, when addressed, is obliged to generate an acknowledge after the reception of each byte. The master 
    

    device must generate an extra clock pulse that is associated with this acknowledge bit. 
    

    A device that acknowledges must pull down the SDA line during the acknowledge clock pulse in such a way that the SDA line is stable LOW 
    

    during the HIGH period of the acknowledge-related clock pulse. Of course, setup and hold times must be taken into account. A master must 
    

    signal an end of READ access to the slave by not generating an acknowledge bit on the last byte that has been clocked out of the slave. In this 
    

    case, the slave must leave the data line HIGH to enable the master to generate the STOP condition.
    

    Figure 10.  Data Read (Write Pointer, Then Read) - Slave Receive and Transmit
    

    Depending upon the state of the R/W bit, two types of data transfer are possible:
    

    n Data transfer from a master transmitter to a slave receiver: The first byte transmitted by the master is the slave address, followed by R/
    

    W = 0. Next follows a number of data bytes. The slave returns an acknowledge bit after each received byte. If the slave does not understand 
    

    the command or data it sends a not acknowledge. Data is transferred with the most significant bit (MSB) first.
    

    n Data transfer from a slave transmitter to a master receiver: The master transmits the first byte (the slave address). The slave then 
    

    returns an acknowledge bit, followed by the slave transmitting a number of data bytes. The master returns an acknowledge bit after all 
    

    received bytes other than the last byte. At the end of the last received byte, a not acknowledge is returned. The master device generates 
    

    all of the serial clock pulses and the START and STOP conditions. A transfer is ended with a STOP condition or with a repeated START 
    

    condition. Since a repeated START condition is also the beginning of the next serial transfer, the bus is not released. Data is transferred with 
    

    the most significant bit (MSB) first.
    

    The AS5013 can operate in the following two modes:
    

    n Slave Receiver Mode (Write Mode): Serial data and clock are received through SDA and SCL. Each byte is followed by an acknowledge 
    

    bit (or by a not acknowledge depending on the address-pointer pointing to a valid position). START and STOP conditions are recognized as 
    

    the beginning and end of a serial transfer. Address recognition is performed by hardware after reception of the slave address and direction 
    

    bit (see Figure 11). The slave address byte is the first byte received after the START condition. The slave address byte contains the 7-bit 
    

    AS5013 address, which is stored in the OTP memory. 
    

    The 7-bit slave address is followed by the direction bit (R/W), which, for a write, is 0. After receiving and decoding the slave address byte the 
    

    device outputs an acknowledge on the SDA. After the AS5013 acknowledges the slave address + write bit, the master transmits a register 
    

    address to the AS5013. This sets the address pointer on the AS5013. If the address is a valid readable address the AS5013 answers by 
    

    sending an acknowledge. If the address-pointer points to an invalid position a not acknowledge is sent. The master may then transmit zero 
    

    or more bytes of data. In case of the address pointer pointing to an invalid address the received data are not stored. The address pointer will 
    

    increment after each byte transferred independent from the address being valid. If the address-pointer reaches a valid position again, the 
    

    AS5013 answers with an acknowledge and stores the data. The master generates a STOP condition to terminate the data write.
