5. Display duty set
(writes display duty value to duty cycle register)
Display duty adjusts contrast in 8 stages using 3-bit data.
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.
