The TVP5154EVM was designed with test points and jumpers to help in evaluation and troubleshooting.
Each jumper is set by default in its preferred state for the TVP5154EVM. There are test points for SCL,
SDA, 3.3 V, and 1.8 V. All digital video data for each decoder core are brought out to a dual-row header,
which allows easy hookup to test equipment. The I
2 C address selection is made with two shunt jumpers,
which are only read after a reset or at power up. The default address is 0xB8. If the address needs to be
changed, the TVP5154 must receive a reset.
