TEA6810V; TEA6811V
I2C-BUS ORGANIZATION
The TEA6810V; TEA6811V is controlled via the I2C-bus which is driven from the TEA6821V. For programming purposes
a module address and four data bytes are required. When used partially, the transmission must be ended by a stop
condition.

I2C-bus address and received bytes
Notes
1. N1 divider ratio is (N + 2); where N is the programmed binary number composed of bytes 1 and 2. For the minimum
ratio; if N < 2048 then N1 divider ratio is {2048 + (N
2)}.
2. X = don’t care.
