5. Display duty set
(writes display duty value to duty cycle register)
Display duty adjusts brightness in 256 stages using 8-bit data. (maximum brightness=240/256)
When power is turned on or when the
RESET
signal is input, the duty cycle register value is
"0". Always execute this instruction before turning the display on, then set a desired duty
value.
