[AK7600]
■ Write Sequence
In the AK7600, when a “Write-Slave-address assignment” is received at the first byte, the write command at the second
byte and data at the third and succeeding bytes are received. At the data block, address and write data are received in a
single-byte unit each in accordance with a command code. The number of write data bytes (*1 in Figure 20)is fixed by the
received command code.
Usable command codes in write sequence are listed below as “Table 3. List of Usable Command Codes in Write
Sequence”.
