After outputting the slave address, the master device transmits the TRC0 bit (bit 3 of IIC status register 0 (IICS0)),
Figures 14-27 and 14-28 show timing charts of the data communication.
IIC shift register 0 (IIC0)’s shift operation is synchronized with the falling edge of the serial clock (SCL0). The
Data input via the SDA0 pin is captured into IIC0 at the rising edge of SCL0.
