AS5600L − Detailed Description

After receiving and decoding the slave address byte, the slave

device drives an acknowledge on the SDA line. The AS5600L

then begins to transmit data starting with the register address

pointed to by the address pointer. If the address pointer is not

written before the initiation of a read transaction, the first

address that is read is the last one stored in the address pointer.

The AS5600L must receive a not acknowledge (NACK) to end a

read transaction.
