ANMG04 (4-CH Auto Sensitivity Calibration Capacitive Touch Sensor)
9 I2C Interface
9.1 I2C Enable / Disable
If the SDA or SCL signal goes to low, I2C control block is enabled automatically. And if the SDA and SCL
signal maintain high during about 2 us, I2C control block is disabled automatically also.
9.2 Start & stop condition
Start Condition (S)
Stop Condition (P)
Repeated Start (Sr)
9.3 Data validity
The SDA should be stable when the SCL is high and the SDA can be changed when the SCL is low.
9.4 Byte format
The byte structure is composed with 8Bit data and an acknowledge signal.
9.5 Acknowledge
It is a check bit whether the receiver gets the data from the transmitter without error or not. The receiver will
