This register is for setting of data output to the LCD static drive port (set by the LCRS register). The LCD
static drive is executed by inverting output of the specified data periodically.
Common output pins are not specified especially. Assign common output to one of segments. For
example, if ST0 to ST8 are assigned static drive pins, ST8 is a common pin and set to LDR0:ST8 = "0".
Furthermore, by setting LDR1: ST [7:0] = "11111111", the LCD selected with ST0 to ST7 is displayed.
