Display timing in Normal mode (not reverse mode), 1/64 duty.
The EM65570S has an RC oscillator. The output from this oscillator is used as the
timing signal source of the display and the boosting clock to the booster.
When external clock is used, feed the clock to CK pin.
The duty cycle of the external clock must be 50%.
The resistance ratio of CR oscillator is programmable. If change this ratio, also change
frame frequency for display.
