(1)

: ON/OFF switch for Rch video output without a reference pulse

(Operates when PICON = 1, set to OFF mode at power-on.)

0 = Rch video output OFF (Blanked status, reference pulse only output)

1 = Rch video output ON

(1)

: ON/OFF switch for Gch video output without a reference pulse

(Operates when PICON = 1, set to OFF mode at power-on.)

0 = Gch video output OFF (Blanked status, reference pulse only output)

1 = Gch video output ON

(1)

: ON/OFF switch for Bch video output without a reference pulse

(Operates when PICON = 1, set to OFF mode at power-on.)

0 = Bch video output OFF (Blanked status, reference pulse only output)

1 = Bch video output ON

(1)

: ON/OFF switch for RGB output with a reference pulse (Set to OFF mode at

power-on.)

0 = RGB output OFF (All blanked status)

1 = RGB output ON

(1)

: V sawtooth wave oscillation stop ON/OFF switch (Set to ON mode at

power-on.)

0 = Oscillation stop OFF (VDRIVE– and VDRIVE+: normal output)

1 = Oscillation stop ON (VDRIVE– and VDRIVE+: DC output and DC value

vary according to V-POSITION.)

(1)

: H oscillator frequency fixation ON/OFF switch (Set to ON mode at power-on.)

0 = H oscillator frequency fixation OFF AFC normal mode

1 = H oscillator frequency fixation ON Oscillator frequency fixed to

maximum value (16.252kHz).

(1)

: V countdown system mode selector switch

(Set to automatic selection mode during power-on.)

0 = Non-standard signal mode, standard signal mode and no signal mode

automatically selected

1 = Fixed to non-standard signal mode

(V oscillator frequency is 55Hz during no signal mode (free run).)
