◆ CSL_dss_overlayRegs

typedef CSL_dss_ovr1Regs CSL_dss_overlayRegs

DSS Overlay Registers.

DSS7 has four identical Overlay blocks, hence define a generic structure to have common APIs

Function Documentation

enable	Enable or disable the color bar

Returns: None

◆ CSL_dssOverlaySetLayerConfig()

void CSL_dssOverlaySetLayerConfig	(	CSL_dss_overlayRegs *	overlayRegs,
		const CSL_DssOverlayLayerCfg *	layerCfg
	)
