DESCRIPTION
VC0
INTREQ
RDY
Parallel host interface C timing is shown in Figure 2–29. The cycle is initiated by the host when VC2-DS transitions
low. The TVP5031 responds by pulling VC0-RDY low. The TVP5031 will then set VC0-RDY to high impedance, a
pullup resistor is required, to indicate the data was received or that the requested data is present on the bus. The host
then completes the cycle by pulling VC2-DS high.
