I2C BUS START-UP TIMING

After Power is turned ON, PT2318 needs to wait for a short time in order to insure stability. This waiting

period is relative to the value of Cref. When Cref=10 µF, the waiting time period for PT2318 to send I2C

Bus Signal is at least 300ms. If the waiting time period is less than 300ms, I2C Control may fail. Please

refer to the figure below.
