Full field mode
This register programs the specific VBI standard for full field mode. It can be any VBI standard. Individual
line settings take priority over the full field register. This allows each VBI line to be programmed
independently but have the remaining lines in full field mode. The full field mode register has the same
definitions as the line mode registers (default 7Fh).

This register controls which of the four decoder cores receives I2C write transactions. A 1 in the
corresponding bit position enables the decoder to receive write commands.
Any combination of decoders can be configured to receive write commands, allowing all four decoders to
be programmed concurrently.

Decoder 1
This register controls which of the four decoder cores responds to I2C read transactions. A 1 in the
corresponding bit position enables the decoder to respond to read commands.
If more than one decoder is enabled for reading, only the lowest numbered decoder responds. Reads from
multiple decoders at the same time is not possible.
Note that when register 0xFE is written to with any value, register 0xFF is set to 0x00. Likewise, when
register 0xFF is written to with any value, register 0xFE is set to 0x00.
To write to the TVP5154 indirect registers, it is required that the registers be unlocked using a password.
The password prevents undesirable writes into the device at start-up due to power surges, for example.
The following example demonstrates the method for unlocking the indirect registers.
After writing to the desired indirect registers described in the following text, it is recommended that the
device be locked again.
Unlock the device
1. Write 0x51 to I2C_0x21. //MSB data
2. Write 0x54 to I2C_0x22. //LSB data
3. Write 0xFF to I2C_0x23. //Data address
4. Write 0x04 to I2C_0x24. //Write command
