GLBCE requires approximately 5400 clock pulses after startup before it could receive data on its video port. Therefore, before RFE -> GLBCE -> FCP path could be used after a GLBCE reset, the SW shall use the following sequence to provide those required clock pulses:
GLBCE has a minimum input restriction of 480x240 pixels. The input frame must be at least this size.
GLBCE LUTs must not be changed during the active frames. They can only be updated in vertical blanking. GLBCE_LUT_FI may be changed frame by frame depending on the GLBCE tuning method. Other LUTs (GLBCE_REV_PERCEPT_LUT_xx, GLBCE_FWD_PERCEPT_LUT_xx, and GLBCE_WDR_GAMMA_LUT_xx) are not expected to be updated dynamically except in very limited case.
