Data write mode
For writing data to a device, four bytes must be sent. Figure 14 explains the data write mode in a signal diagram:
One byte with the device address, being ‘00000110’, which is including the LSB code 01 for signalling write to the
device
One byte starting with a logic 0 for signalling write, followed by 7 bits indicating the destination address
Two data bytes.
The SYSCLK signal must be applied in data write mode.

Data read mode
For reading from the device, first a prepare-read must be
done. After this, the device address is sent again. The
device then returns with the register address, indicating
whether the address was valid or not, and the data of the
register. The following five steps explain this procedure,
and an example of transmission is given in Fig.15.
One byte with the device address, being ‘00000110’,
which is including the LSB code 01 for signalling write to
the device
One byte is sent with the register address from which it
needs to be read. This byte starts with a logic 1, which
indicates that there will be a read action from the register
One byte with the device address including ‘11’ is sent
to the device, being 00000111. The ‘11’ indicates that
the device must write data to the microcontroller, then
the microcontroller frees the L3DATA-bus so the
UDA1380 can send the register address byte and its
two-byte contents
The device now writes the requested register address
on the bus, indicating whether the requested register
was valid or not (logic 0 means valid, logic 1 means
invalid)
The device writes the data from the requested register
on the bus, being two bytes.
The SYSCLK signal must be applied in data read mode.
