... Output Report‟ HID request issued by USB host.CM6206 will then assert MINT to inform MCU to read them. CM6206 has one input pin „SCLK‟ to get serial clock from MCU, and one open-drain output pin „SDAT‟ to send or receive serial signal to/from MCU. As shown below, „SDAT‟ should be stable when „SCLK‟ is high, and can have transition only when „ ...

... Positive acknowledge Byte One byte data In a write transfer, MCU keeps acting as the transmitter. CM6206 regards the first DATA byte as start register address. The second and third DATA bytes are the content that MCU writes to the register addresses read transfer, two transactions are necessary. MCU resets start register address by the first transaction. ...
