Host Interface
The host interface is used to initialize the internal microprocessor, to read and write status registers and control
registers, and to access sliced VBI data.
The interface modes supported by the TVP5031 are I
2
C, and three parallel interface modes. The host interface is
configured at powerup and reset using the GLCO, PALI, and the FID terminals as shown in Table 2–2.

C Host Interface
The TVP5031 host interface is configured for I
2
C operation by attaching external pullup and pulldown resistors to the
GLCO, PALI, and FID terminals. The following is the combination of resistors required to select I
2
C host mode (1 is
pullup and 0 is pulldown).

C Host Port Select
The I
2
C standard consists of two signals, serial input/output data line (VC1) and input/output clock line (VC0), which
carry information between the devices connected to the bus. A third signal (VC3) is used for slave address selection.
Although the I
2
C system can be multi-mastered, the TVP5031 will function as a slave device only.
Both SDA and SCL are bidirectional lines connected to a positive supply voltage via a pull up resistor. When the bus
is free, both lines are high.
The slave address select terminal (VC3) enables the use of two TVP5031 devices tied to the same I
2
C bus.
