With the HSYNCO output, the meaning of the signal source to be selected and use or non-use of
modification varies according to the IHI signal source and the waveform required by external
circuitry. The HSYNCO output modes are shown in table 14.10.

Meaning of IHO Signal
HFBACKI input is output directly
Meaningless unless there is a double-frequency
part in the HFBACKI input
HFBACKI input 1 interval is changed before output
Internal synchronization signal is output
CSYNCI input (composite synchronization signal)
is output directly
Double-frequency part of CSYNCI input (composite
synchronization signal) is eliminated before output
CSYNCI input (composite synchronization signal)
horizontal synchronization signal part is separated
before output
Internal synchronization signal is output
HSYNCI input (composite synchronization signal)
is output directly
Double-frequency part of HSYNCI input (composite
synchronization signal) is eliminated before output
HSYNCI input (composite synchronization signal)
horizontal synchronization signal part is separated
before output
Internal synchronization signal is output
HSYNCI input (horizontal synchronization signal) is
output directly
Meaningless unless there is a double-frequency
part in the HSYNCI input (horizontal
synchronization signal)
HSYNCI input (horizontal synchronization signal) 1
interval is changed before output
Internal synchronization signal is output
