TM1637 Datasheet

The data transmission of TM1637 has an acknowledgment signal ACK. When the transmitted data is correct, on the falling edge of the eighth clock, an acknowledgment signal ACK will be generated inside the chip to pull the DIO pin low, and the DIO will be released after the end of the ninth clock.
