I am in the process of designing an embedded system around the 68HC11 and decided to use the CFAH2004A-TMI-JP, controlled through 8 port pins. Are there any design requirements/hints I should know about? For example, would you suggest a latch on these lines?
Also, the MCU is being programmed in assembly, and I am not sure about getting the timing right(the 2MHz chip processes a command every 500ns, a little fast for the HD44780). Are there any resources availiable for this MCU/LCD combo in assembly? Everything I can find is in BASIC or C++. Thanks!
