HSA[7:0], HEA[7:0]: HSA[7:0] and HEA[7:0] specify the start and end addresses of the window address
area in horizontal direction, respectively. See GRAM Address Map
. HSA[7:0] and HEA[7:0] specify the
horizontal range to write data. Set HSA[7:0] and HEA[7:0] before starting RAM write operation. In
setting, make sure that 8’h00
≤
HSA < HEA
≤
8’hEF.
VSA[8:0], VEA[8:0]: VSA[8:0] and VEA[8:0] specify the start and end addresses of the window address
area in vertical direction, respectively. See GRAM Address Map
. VSA[8:0] and VEA[8:0] specify the
vertical range to write data. Set VSA[8:0] and VEA[8:0] before starting RAM write operation. In setting,
make sure that 9’h000 ≤ VSA < VEA ≤ 9’h1AF.
