Datasheet - Detailed Description
Figure 11. Data Write - Slave Receiver Mode
n Slave Transmitter Mode (Read Mode): The first byte is received and handled as in the slave receiver mode. However, in this mode, the 
direction bit indicates that the transfer direction is reversed. Serial data is transmitted on SDA by the AS5013 while the serial clock is input
on SCL. START and STOP conditions are recognized as the beginning and end of a serial transfer. The slave address byte is the first byte
received after the master generates a START condition. The slave address byte contains the 7-bit AS5013 address. The default address is
80h. The 7-bit slave address is followed by the direction bit (R/W), which, for a read, is 1. After receiving and decoding the slave address
byte the device outputs an acknowledge on the SDA line. The AS5013 then begins to transmit data starting with the register address
pointed to by the register pointer. If the register pointer is not written to before the initiation of a read mode the first address that is read is the
last one stored in the register pointer. The AS5013 must receive a not acknowledge to end a read.
