When MADCTL ML=0 －The 1 st & 2nd parameter TFA [7:0] describes the Top Fixed Area (in No. of lines from Top of the Frame Memory and Display). －The 3 rd & 4th parameter VSA [7:0] describes the height of the Vertical Scrolling Area (in No. of lines of the Frame Memory [not the display] from the Vertical Scrolling Start Address) －The first line appears immediately after the bottom most line of the Top Fixed Area. －The 5 th & 6th parameter BFA [7:0] describes the Bottom Fixed Area (in No. of lines from Bottom of the Frame Memory and Display). －TFA, VSA and BFA refer to the Frame Memory row address. When MADCTL ML=1 －The 1 st & 2nd parameter TFA [7:0] describes the Top Fixed Area (in No. of lines from Bottom of the Frame Memory and Display). －The 3 rd & 4th parameter VSA [7:0] describes the height of the Vertical Scrolling Area (in No. of lines of the Frame Memory [not the display] from the Vertical Scrolling Start Address) －The first line appears immediately after the top most line of the Top Fixed Area. －The 5 th & 6th parameter BFA [7:0] describes the Bottom Fixed Area (in No. of lines from Top of the Frame Memory and Display). See Section 9.10.4 for details of the Memory to Display Mapping. -The condition is 0≦(TFA+VSA+BFA) ≦132, otherwise Scrolling mode is undefined. -In Vertical Scroll Mode, MADCTL parameter MV should be set to ‘0’-this only affects the Frame Memory Write.
