Table 3.14.3 shows the relationship between the number of clocks for data transfer
I2C0CR1<BC> is cleared to 0y000 by a start condition.
This means that the slave address and direction bit are always transferred as 8-bit
A slave address must be transmitted/received with I2C0CR1<ACK> set to 1. If I2C0CR1<ACK> is
cleared, the slave address match detection and direction bit detection cannot be performed properly.
