2、SIs and display data Memory, It has an 8 bit parallel data busAnd control lines for reading or writing through a MPU I/F.It has 128 words character generator ROM with the capability to controlExternal display RAM of up to 128K bytes. Allocation of text, graphics And external generator RAM can be eas

3、ily made and the display window canBe freely moved within the allocated memory range. It supports a very board range of LCD formats by selecting differentCombinations on a set of programmable inputs. It can be used in text,graphicModes and has various attribute functions. 指令表：表 2COMMANDCODED1D2FUNCT
