the BAR pin is disabled
the BAR pin has an action on the line PLL
the missing sync pulsesare not detected
the missing sync pulsesare detected
the MUTEpin is forced to 0
the MUTEpin delivers the internal MUTEsignal
the MUTE time constant is 8 lines
the MUTE time constant is 32 lines
the sync is not re-inserted
the sync is re-inserted for improved text stability
the gain of pins VIDEO OUT1 & VIDEOOUT2 is 0dB.
the gain of pins VIDEO OUT1 & VIDEOOUT2 is 6dB.
the color encoderis enabled (PALor NTSC)
the color encoderis disabled(B&W or SECAM)
the VIDEOOUT2 pinoutputs the VIDEOIN signal
the VIDEOOUT2 pinoutputs the compositesync
the VIDEOOUT2 pinis inhigh impedancestate
the VIDEOOUT2 pinis inlow impedancestate
M9 : This Mode bit has to be keptat a low level.

:
It enablesthe delay compensationof the internalsync extractor.
M11 : M11 = 0

:
The mute signal is not synchronized on vertical sync thus accelerating the VIDEO IN
presence detection(useful in full page mode).

:
No delaycompensation
:
The mute signal output is synchronizedon verticalsync in order to limit its transitions.
2 - THE MICROPROCESSOR SERIAL INTERFACE
The STV5730 is down loaded by the microprocessor through a three wire serial interface : DATA, CLK,
CSN. The CLK andCSN signals are internallyORed in order to validate the transferwhen the STV5730 is
chipselected only (i.e. CSN = 0). The CSN rising edge validates theinternal data transfer.
2.1 - MessageFormats
(seeFigure 2)
16-bit,8-bit and 0-bit formats are available. The 8-bit and 0-bit message formatsmay be useful to speed
up the STV5730 down loading.
