Internal Control Registers
7.1
Overview
The TVP5154A decoder is initialized and controlled by sets of internal registers that set all device
operating parameters. Communication between the external controller and the TVP5154A decoder is
through the I2C. Two sets of registers exist, direct and indirect. Table 7-1 shows the summary of the direct
registers. 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.
I2C register FEh controls which of the four decoders receives I2C commands. I2C register FFh controls
which decoder core responds to I2C reads. Note, for a read operation, it is necessary to perform a write
first, to set the desired sub-address for reading.
After power up and the hardware reset, each decoder must be started by writing 00h to register 7Fh for all
four decoders.
