After outputting the slave address, the master device transmits the IICSn.TRCn bit, which specifies the data transfer
The shift operation of the IICn register is synchronized with the falling edge of the serial clock pin (SCL0n). The
Data input via the SDA0n pin is captured by the IICn register at the rising edge of the SCL0n pin.
The data communication timing is shown below.
