Data transfers occur utilizing the following illustrated formats.
An I2C master initiates a write operation to the TVP5150AM1 decoder by generating a start condition (S)
followed by the TVP5150AM1 I2C address (see the following illustration), in MSB-first bit order, followed
by a 0 to indicate a write cycle. After receiving an acknowledge from the TVP5150AM1 decoder, the
master presents the subaddress of the register, or the first of a block of registers it wants to write, followed
by one or more bytes of data, MSB first. The TVP5150AM1 decoder acknowledges each byte after
completion of each transfer. The I2C master terminates the write operation by generating a stop condition
(P).

Repeat steps 6 and 7 until all data have been written.
The read operation consists of two phases. The first phase is the address phase. In this phase, an I2C
master initiates a write operation to the TVP5150AM1 decoder by generating a start condition (S) followed
by the TVP5150AM1 I2C address, in MSB-first bit order, followed by a 0 to indicate a write cycle. After
receiving acknowledges from the TVP5150AM1 decoder, the master presents the subaddress of the
register or the first of a block of registers it wants to read. After the cycle is acknowledged, the master
terminates the cycle immediately by generating a stop condition (P).
