executed in 8 bits. Other than these, the BC retains a specified value.
The BC (Bits7 to 5 in SBICRA) is used to select a number of bits for next transmitting and receiving data.
Since the BC is cleared to “000” by a start condition, a slave address and direction bit transmissions are always

in the master mode.
which is input from SCL pin.
To set the device as a non-acknowledgement mode, the ACK (Bit4 in SBICRA) should be cleared to “0”.
In the master mode, a clock pulse for an acknowledge signal is not generated.
In the slave mode, a clock for a acknowledge signal is not counted.
The SCK (Bits2 to 0 in SBICRA) is used to select a maximum transfer frequency output from the SCL pin
Four or more machine cycles are required for both high and low levels of pulse width in the external clock
Note:Since the serial bus interface can not be used as the fast mode and the high-speed mode, do not set
Non-acknowledgment mode (ACK = “0”)
Clock source
Note 1: fc = High-frequency clock
Note 2: tcyc = 4/fc (in NORMAL mode, IDLE mode)
SCK as the frequency that is over 100 kHz.

t LOW = 2 /fc
t HIGH = 2 /fc + 8/fc
