Setting the Acknowledgement Mode
Setting the Number of Bits per Transfer
Serial Clock
Setting SBIxCR1<ACK> to “1” selects the acknowledge mode. When operating as a master,
the SBI adds one clock for acknowledgment signals. As a transmitter, the SBI releases the
SDA pin during this clock cycle to receive acknowledgment signals from the receiver. As a
receiver, the SBI pulls the SDA pin to the “L” level during this clock cycle and generates
acknowledgment signals.
By setting <ACK> to “0”, the non-acknowledgment mode is activated. When operating as a
master, the SBI does not generate clock for acknowledgement signals.
SBIxCR1 <BC2:0> specifies the number of bits of the next data to be transmitted or
received.
Under the start condition, <BC2:0> is set to “000,” causing a slave address and the direction
bit to be transferred in a packet of eight bits. At other times, <BC2:0> keeps a previously
programmed value.

The highest speeds in the standard and high-speed
modes are specified to 100KHz and 400KHz respectively
following the communications standards. Note that the
internal SCL clock frequency is determined by the fsys
used and the calculation formula shown above.
