devices as its communication partner.
that specifies the data transfer direction and then starts serial communication with the slave device.
The transmit data is transferred to the SO latch and is output (MSB first) via the SDA pin.
When using I
After outputting the slave address, the master device transmits the TRC bit (bit 3 of IIC status register 0 (IICS0))
The shift operation of IIC bus shift register 0 (IIC0) is synchronized with the falling edge of the serial clock (SCL).
Data input via the SDA pin is captured by IIC0 at the rising edge of SCL.
The following shows the timing charts of data communication.
