transmit data is transferred to the SO0 latch and is output (MSB first) via the SDA0 pin.
When using the I
After outputting the slave address, the master device transmits the TRC0 bit (bit 3 of IIC status register 0 (IICS0)),
Figures 12-28 and 12-29 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.
