3.20 Internal Control Registers
The TVP5151 decoder is initialized and controlled by a set of internal registers that set all device operating
parameters. Communication between the external controller and the TVP5151 decoder is through I
2
C.
Table 3-11 shows the summary of these registers. The reserved registers must not be written. Reserved
bits in the defined registers must be written with zeros, unless otherwise noted. The detailed programming
information of each register is described in the following sections.
