I/O
(1) When bus HD-OUT=0, outputs the HD pulse imposed with
AFC (pulse width:1 us).
O
Also provided with a BPP (black peak detection stop pulse)
signal external input function.
(2) When bus HD-OUT=1, and AKB is ON, outputs the AKB
reference period pulse.
O
Outputs the sync signal separated in the sync separation circuit.
