void XV_HdmiTxSs1_SetVideoStreamScramblingOverrideFlag	(	XV_HdmiTxSs1 *	InstancePtr,
		u8	OverrideScramble
	)

This function Sets the HDMI TX SS video stream scrambling behaviour.

Setting OverrideScramble to true will force enabling/disabling scrambling function based on the value of IsScrambled flag.

Parameters

InstancePtr	pointer to XV_HdmiTxSs1 instance
OverrideScramble	0: Scrambling is always enabled for HDMI 2.0 resolutions and is enabled /or disabled for HDMI 1.4 resolutions based on IsScrambled value 1: Enable scrambling if IsScrambled is TRUE and disable scrambling if IsScrambled is FALSE

Returns

None.

Note
