Interface interpretation of TM1637 4 Digit 7 Segment Display

Microprocessor data realize the communication with TM1637 4 Digit by means of two–wire bus interface (Note: The communication method not equal to 12C bus protocol totally because there is no slave address).When data  input, DIO signal should not change for high level CLK and DIO signal should change for low level CLK signal. When CLK is a high level and DIO changes from high to low level, data input starts. When CLK is a high level and DIO changes from low level to high level, data input ends.TM1637 data transfer carries with answering signal ACK. For a right data transfer, an answering signal ACK  generate inside the chip to lower the DIO pin at the failing edge of the 8th clock. DIO interface wire  release at the end of the 9th clock
