Powers down the decoder
Resets the decoder
Normal operation
The TVP5154 decoder is initialized and controlled by sets of internal registers that set all device operating
parameters. Communication between the external controller and the TVP5154 decoder is through the I
2
C.
Two sets of registers exist, direct and indirect.
Table 9-1
shows the summary of the direct registers.
Reserved registers must not be written. Reserved bits in the defined registers must be written with 0s,
unless otherwise noted. The detailed programming information of each register is described in the
following sections.
I
2
C register 0xFE controls which of the four decoders receives I
2
C commands. I
2
C register 0xFF controls
which decoder core responds to I
2
C reads. Note, for a read operation, it is necessary to perform a write
first, in order to set the desired sub-address for reading.
After power up and the hardware reset, each decoder must be started by writing 0x00h to register 7Fh for
all four decoders.
