I Input pulse to DIM pin
The pulse input to DIM pin is allowed after startup time 1msec that is for initializing IC interior with ENA pin
at High level. The output voltage is setup at the initial value DATA0: 85V. The pulse input to DIM pin changes
the output pin voltage setting, so that the EL brightness can be adjusted.
