Automatic increment of address pointer:
The AS5510 slave automatically increments the address pointer after each byte transferred. The increase of the
address pointer is independent from the address being valid or not.
Invalid Addresses:
If the user sets the address pointer to an invalid address, the address byte is not acknowledged. Nevertheless a
read or write cycle is possible. The address pointer is increased after each byte.

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 AS5510 while
the serial clock is input on SCL. START and STOP conditions are recognized as the beginning and end of
a serial transfer (Figure 8.
Figure 9.
byte is the first byte received after the master generates a START condition. The slave address byte
contains the 7-bit AS5510 address. 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 AS5510 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 AS5510 must receive a “not
acknowledge” to end a read.
