I2C Read Operation
The read operation has two phases, the address phase and the data phase. In the address phase, the I2C
master initiates a write operation to the TVP5020 by generating a start condition followed by the TVP5020’s
I2C address (101110X). The address is in MSB first bit order followed by a 0 to indicate a write cycle. After
receiving a TVP5020 acknowledge, the I2C master sends a subaddress of the register or the block of
registers where it will read. The TVP5020 acknowledges the receipt of the address. The I2C master ends
the address phase by generating a stop condition. During the data phase, the I2C master initiates a read
operation to the TVP5020 by generating a start condition followed by the TVP5020’s I2C address (101110X).
The address is in MSB first bit order followed by a 1 to indicate a read cycle. After receiving a TVP5020
acknowledge, the TVP5020 transfers a data byte to the master. The I2C master acknowledges the receipt
of each byte upon completion of each transfer. After the TVP5020 transfers the last byte, the I2C master ends
the read operation by generating a not acknowledge followed by a stop condition.
