not work.
function signal (DPS) must be Low or High-impedance, exclude the VALID period (See
above sequence diagram), in order to avoid that internal circuits is damaged.
If some of display and function signals of this product are cut while this product is working,
even if the signal input to it once again, it might not work normally. VCC should be cut when
the display and function signals are stopped.
