M0 : M0 = 0 : the BAR pin is disabled
M0 = 1 : the BAR pin has an action on the line PLL
M1 : M1 = 0 : the missing sync pulses are not detected
M1 = 1 : the missing sync pulses are detected
M2 : M2 = 0 : the MUTE pin is forced to 0
M2 = 1 : the MUTE pin delivers the internal MUTE signal
M3 : M3 = 0 : the MUTE time constant is 8 lines
M3 = 1 : the MUTE time constant is 32 lines
M4 : M4 = 0 : the sync is not re-inserted
M4 = 1 : the sync is re-inserted for improved text stability
M5 : M5 = 0 : the gain of pins VIDEO OUT1 & VIDEO OUT2 is 0dB.
M5 = 1 : the gain of pins VIDEO OUT1 & VIDEO OUT2 is 6dB.
M6 : M6 = 0 : the color encoder is enabled (PAL or NTSC)
M6 = 1 : the color encoder is disabled (B&W or SECAM)
M7 : M7 = 0 : the VIDEO OUT2 pin outputs the VIDEO IN signal
M7 = 1 : the VIDEO OUT2 pin outputs the composite sync
M8 : M8 = 0 : the VIDEO OUT2 pin is in low impedance state
M8 = 1 : the VIDEO OUT2 pin is in high impedance state
M9 : M9 = 0 : Normal mode
M9 = 1 : CSYNC Pin outputs the burst gate, BAR Pin outputs the VSYNC (see Note)
M10 : M10 = 0 : No delay compensation
M10 = 1 : It enables the delay compensation of the internal sync extractor.
M11 : M11 = 0 : The mute signal output is synchronized on vertical sync in order to limit its transitions.
M11 = 1 : The mute signal is not synchronized on vertical sync thus accelerating the VIDEO IN
presence detection (useful in full page mode).
Note : This mode overides the normal functions of Pins CSYNC and BAR.
