Any register above address 0x08 is reserved for testing and should not be written to because it may change the
function of the device. If read, these bits may assume any value.
Some of the default values can be reprogrammed through the I
2
C interface and written to the EEPROM. This
function is useful to speed up the turn-on time of the device and minimizes the number of I
2
C writes. If this is
required, contact your local TI representative.
The TPA2016D2 I
2
C address is 0xB0 (binary 10110000) for writing and 0xB1 (binary 10110001) for reading. If a
different I
2
C address is required, please contact your local TI representative. See the General I2C operation
section for more detail.
The following tables show the details of the registers, the default values, and the values that can be programmed
through the I
2
C interface.
