436 / 1075 page  Section 13 Timer Connection Rev. 3.00 Jan 18, 2006 page 408 of 1044 REJ09B0280-0300 Mode IVI Signal IVO Signal Meaning of IVO Signal Separate mode VSYNCI input IVI signal (without fall modification or IHI synchronization) VSYNCI input (vertical synchronization signal) is output directly IVI signal (without fall modification, with IHI synchronization) Meaningless unless VSYNCI input (vertical synchronization signal) is synchronized with HSYNCI input (horizontal synchronization signal) IVI signal (with fall modification, without IHI synchronization) VSYNCI input (vertical synchronization signal) fall is modified before output IVI signal (with fall modification and IHI synchronization) VSYNCI input (vertical synchronization signal) fall is modified and signal is synchronized with HSYNCI input (horizontal synchronization signal) before output IVG signal Internal synchronization signal is output 13.3.9 CBLANK Output Using the signals generated/selected with timer connection, it is possible to generate a waveform based on the composite synchronization signal (blanking waveform). One kind of blanking waveform is generated by combining HFBACKI and VFBACKI inputs, with the phase polarity made positive by means of bits HFINV and VFINV in TCONRI, with the IVO signal. The composition logic is shown in figure 13.9.
