Multichannel audio coder-decoder
9.4 Data write mode
The data write mode is explained in the signal diagram of
Figure 11
. For writing data to a
device, 4 bytes must be sent (see
Table 14
):
1. Byte 1 starting with ‘01’ for signalling the write action to the device, followed by the
device address ‘01 0100’
2. Byte 2 starting with a ‘0’ for signalling the write action, followed by 7 bits indicating the
destination address in binary format with bit A6 being the MSB and bit A0 being the
LSB
3. Byte 3 with bit D15 being the MSB
4. Byte 4 with bit D0 being the LSB
It should be noted that each time a new destination register address needs to be written,
the device address must be sent again.
9.5 Data read mode
To read data from the device, a prepare read must first be done and then data read. The
data read mode is explained in the signal diagram of
Figure 12
.
For reading data from a device, the following 6 bytes are involved (see
Table 15
):
1. Byte 1 with the device address, including ‘01’ for signalling the write action to the
device.
2. Byte 2 is sent with the register address from which data needs to be read. This byte
starts with a ‘1’, which indicates that there will be a read action from the register,
followed by 7 bits for the destination address in binary format, with bit A6 being the
MSB and bit A0 being the LSB.
3. Byte 3 with the device address, including ‘11’ is sent to the device. The ‘11’ indicates
that the device must write data to the microcontroller.
4. Byte 4 sent by the device to the bus, with the (requested) register address and a flag
bit indicating whether the requested register was valid (bit is logic 0) or invalid (bit is
logic 1).
5. Byte 5 sent by the device to the bus, with the data information in binary format, with
bit D15 being the MSB.
6. Byte 6 sent by the device to the bus, with the data information in binary format, with
bit D0 being the LSB.
