The external synchronizationsignals (DOTCLK, VS and HS) are used for internal display signals. So, controller (host)must always transfer DOTCLK, VS, HS and DE signals to driver.In RGB Mode 2 (RCM1, RCM0 = “11”), blanking porch setting of VS and HS signals aredefined by R33h and R34h command. DE pin is not used.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.52-October, 2009
