Multiple Byte Write
A multiple byte data write transfer is identical to a single byte data write transfer except that multiple data bytes
are transmitted by the master device to slave as shown in Figure 20. After receiving each data byte, the
TAS3218 will respond with an acknowledge bit.
Figure 20. Multiple Byte Write Transfer
Multiple Byte Read
A multiple byte data read transfer is identical to a single byte data read transfer except that multiple data bytes
are transmitted by the TAS3218 to the master device as shown in Figure 21. Except for the last data byte, the
master device will respond with an acknowledge bit after receiving each data byte.
Figure 21. Multiple Byte Read Transfer
Random I2C Transactions
Supplying a subaddress for each subaddress transaction is referred to as random I2C addressing. For random
I2C read commands, the TAS3218 responds with data, a byte at a time, starting at the sub address assigned, as
long as the master device continues to respond with acknowledges. If a given sub address does not use all 32
bits, the unused bits are read as logic 0. I2C write commands, however, are treated in accordance with the data
assignment for that address space. If a write command is received for a biquad sub address, for example, the
TAS3218 expects to see five 32-bit words. If fewer than five data words have been received when a stop
command (or another start command) is received, the data received is discarded.
Sequential I2C Transactions
The TAS3218 supports sequential I2C addressing. For write transactions, if a sub address is issued followed by
data for that sub address and the fifteen sub addresses that follow, a sequential I2C write transaction has taken
place, and the data for all 16 sub addresses is successfully received by the TAS3218. For I2C sequential write
transactions, the sub address then serves as the start address and the amount of data subsequently transmitted,
before a stop or start is transmitted, determines how many sub addresses are written to. As was true for random
addressing, sequential addressing requires that a complete set of data be transmitted. If only a partial set of data
is written to the last sub address, the data for the last sub address is discarded. However, all other data written is
accepted; just the incomplete data is discarded.
Sequential read transactions do not have restrictions on outputting only complete sub address data sets.
If the master does not issue enough data received acknowledges to receive all the data for a given sub address,
the master device simply does not receive all the data.
