2.10 Internal Control Registers
The TVP5146M2 decoder 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 TVP5146M2 is
through a standard I2C host port interface, as previously described. Table 2-10 shows the summary of
these registers. Detailed programming information for each register is described in the following sections.
Additional registers are accessible through an indirect procedure involving access to an internal 24-bit
address wide VBUS. Table 2-11 shows the summary of the VBUS registers.
NOTE
Do not write to reserved registers. Reserved bits in any defined register must be written with
zeros, unless otherwise noted.
