SMBus Operation
The TAS3002 device supports a subset of the SMBus protocol. With proper programming techniques, it is possible
to use the SMBus to set up the TAS3002 device.
6.4.1
Block Write Protocol
The TAS3002 device supports the block write protocol that allows up to 32 bytes to be sent as a block. To send a
command using this format, the most significant bit (MSB) of the TAS3002 subaddress must be set high and the
subaddress (also with MSB set high) must be programmed into the SMBus command byte. This operation signals
the TAS3002 device that the next byte is the SMBus byte-count byte. The next byte after the byte count is then entered
into the device as the first byte of data.

Write Byte Protocol
The TAS3002 device also supports the SMBus write byte protocol. Writing to the main control register (MCR), bass,
and treble registers requires using the byte write protocol. To send a command using this protocol, the most significant
bit (MSB) of the TAS3002 subaddress must be set high and the subaddress (also with MSB set high) must be
programmed into the SMBus command byte. The next byte after the command byte is then entered into the device
as the first byte of data.
