13.3.9
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.

Meaning of IVO Signal
VSYNCI input (vertical synchronization signal)
is output directly
Meaningless unless VSYNCI input (vertical
synchronization signal) is synchronized with
HSYNCI input (horizontal synchronization
signal)
VSYNCI input (vertical synchronization signal)
fall is modified before output
VSYNCI input (vertical synchronization signal)
fall is modified and signal is synchronized with
HSYNCI input (horizontal synchronization
signal) before output
Internal synchronization signal is output
