ATA WRITE MODE
The data write format is given in Table 13 and illustrated
in Fig.9.
When writing data to a device four bytes must be sent:
1.
One byte with the device address, being ‘01X0 1000’
where ‘X’ stands for the IPSEL value, including ‘01’ for
signalling write to the device.
2.
One byte starting with a logic 0 for signalling write
followed by 7 bits indicating the register address.
3.
One byte which is the Most Significant Data (MSD)
byte 1.
4.
One byte which is the Least Significant Data (LSD)
byte 2.

ATA READ MODE
The data write format is given in Table 14 and illustrated
in Fig.10.
Whenreadingfromthedevice,apreparereadmustfirstbe
done. After the prepare read, 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 data read mode is explained below:
1.
One byte with the device address, being ‘01X0 1000’
where ‘X’ stands for the IPSEL value, including ‘01’ for
signalling write to the device.
2.
One byte is sent with the register address which needs
to be read. This byte starts with a logic 1, which
indicates that there will be a read action from the
register.
3.
One byte with the device address including ‘11’ is sent
to the device. The ‘11’ indicates that the device must
write data to the microcontroller.
4.
The device now writes the requested register address
on the L3-bus, indicating whether the requested
register was valid (logic 0) or invalid (logic 1).
5.
The device writes data from the requested register to
the L3-bus with the MSD byte 1 first, followed by the
LSD byte 2.
