13.4.9
Using the signals generated/selected with the timer connection, it is possible to generate an
waveform based on the composite synchronization signal (blanking waveform). This function is
not available in channel 1.
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, and with
the IVO signal.
The logic of CBLANK output waveform generation is shown in figure 13.17.

Meaning of IVO Signal
VSYNCI input (vertical synchronization
signal) is output directly
Meaningless if 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 the signal is
synchronized with HSYNCI input
(horizontal synchronization signal) before
output
Internal synchronization signal is output
