TEA5760UK
Single chip FM stereo radio
8.
I2C-bus interface
The I2C-bus interface is based on
The I2C-bus specication, version 2.1 January 2000,
expanded by the following denitions.
8.1 Write and read mode
8.2 Data transfer
Structure of the I2C-bus:
Slave transceiver
Subaddresses not used
Remark: The I2C-bus operates at a maximum clock rate of 400 kHz. It is not allowed to
connect the TEA5760UK to an I2C-bus operating at a higher clock rate.
Data transfer to the TEA5760UK:
Bit 7 of each byte is considered the MSB and has to be transferred as the rst bit of
the byte.
The LSB indicates the write or read action.
