The firstline read from Frame Memory appears immediately after the bottom most line of theTop Fixed Area.BFA[15:0] describes the Bottom Fixed Area (in No. of lines from Bottom of the FrameMemory and Display).TFA, VSA and BFA refer to the Frame Memory Line Pointer.Please note that (TFA+VSA+BFA) must be set to ‘320d’, otherwise Scrolling mode isundefined. In Vertical Scroll Mode, MV bit should be set to ‘0’ – this only affects theFrame Memory Write.Himax ConfidentialFor Go-tek OnlyThis information contained herein is the exclusive property of Himax and shall not be distributed, reproduced, or disclosedin whole or in part without prior written permission of Himax.-P.129-October, 2009
