The TVP7000 is initialized and controlled by a set of internal registers that define the operating parameters of the
entire device. Communication between the external controller and the TVP7000 is through a standard I2C host
port interface, as described earlier.
Table 5 shows the summary of these registers. Detailed programming information for each register is described
in the following sections.

Register addresses not shown in the register map summary are reserved and must not be written to.
(2)
Writing to or reading from any value labeled “Reserved” register may cause erroneous operation of the TVP7000. For registers with
reserved bits, a 0b must be written to reserved bit locations unless otherwise stated.
