The BC2 to BC0 bits decide how many bits are in one byte data transferred next. After the selected
numbers of bits are transferred successfully, I
BC2 to BC0 bits are reset to "000

In addition, the BC2 to BC0 bits become "000

interface is disabled and the SDA and SCL pins are placed in a high-h-impedance state. When the
ES0 bit is set to “1”, the interface is enabled.
When the ES0 bit is set to “0”, the process is followed.
1)The bits in the S10 register are set as MST = "0", TRX = "0", PIN = "1", BB = "0", AL = "0", AAS = "0",
2)The S00 register cannot be written.
3)The TOF bit in the S4D0 register is set to “0” (time-out detection flag is not detected)
4)The I
The ALS bit determines whether the salve address is recognized. When the ALS bit is set to “0”, an
addressing format is selected and a address data is recognized. Only if the comparison is matched
between the slave address stored into the S0D0 register and the received address data or if the
general call is received, the data is transferred. When the ALS bit is set to "1", the free data format is
selected and the slave address is not recognized.
The IHR bit is used to reset the I
