*2 Line number is 262H or 263H for EIA and 312H or 313H for CCIR.
O : Can be used.
¡ â: The shutter speed may change from
its value in the interlace mode.
X : Cannot be used.
Note ) Only in the VD/HD sync mode, the external synchronization is possible during which VD pulses with longer
cycle than normal are input to the VR/SYNC pin.
