Data Sheet
Figure 6. 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:
The AS5510 can operate in the following two modes:

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 7.
Receiver Mode). The slave address byte is the first byte received after the 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 write, is 0. After receiving and decoding the slave address byte the device outputs an
acknowledge on theSDA. After the AS5510 acknowledges the slave address + write bit, the master
transmits a register address to the AS5510. This sets the address pointer on the AS5510. If the address is
a valid readable address the AS5510 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 AS5510 answers with an acknowledge and stores the data. The
master generates a STOP condition to terminate the data write.
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.
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.
