Figure 16-5 shows the operation timing and control method when an acknowledgment error occurs.
When the values of the transmitted bit and the SDA pin do not coincide, the I20ER bit of the I2C bus 0 status register
(I2C0STAT) is set to “1” and SDA pin remains the output until termination of the subsequent byte data communication
I20ER bit is initialized to “0” by writing I
Figure 16-6 shows the operation timing and control method when transmission fails.
