The second phase is the data phase. In this phase, an I2C master initiates a read operation to the
TVP5150AM1 decoder by generating a start condition followed by the TVP5150AM1 I2C slave address
(see the following illustration of a read operation), in MSB first bit order, followed by a 1 to indicate a read
cycle. After an acknowledge from the TVP5150AM1 decoder, the I2C master receives one or more bytes
of data from the TVP5150AM1 decoder. The I2C master acknowledges the transfer at the end of each
byte. After the last data byte desired has been transferred from the TVP5150AM1 decoder to the master,
the master generates a not acknowledge followed by a stop.
