Note 1: Don't set I2C0AR<SA> to "0x00". If it is set to "0x00", the slave address is deemed to be matched when the I
Note 2: Don't change the contents of the registers when the start condition is generated, the stop condition is generated or the
Note 3: After a software reset is generated, all the bits of the SBI0CR2 register except SBI0CR2<SBIM> and the SBI0CR1, I2C0AR

Note 1: Write the transmit data beginning with the most significant bit (bit 7).
Note 2: SBI0DBR has individual writing and reading buffers, and written data cannot be read out. Therefore, SBI0DBR must not
