When the IC is set to SECAM
identification mode, the 4.43MHz VCO
oscillator waveform is output from this
pin centering on DC 1.5V.
If a 150µA current is led from this pin
during this identification mode, the IC
is set to SECAM mode. In SECAM
mode, the 4.43MHz VCO oscillator
waveform is output centering on
DC = 5V only during the VBLK
interval.
