In the slave mode, the AAS (Bit2 in SBISRB) is set to “1” when the received data is “GENERAL CALL” or
When a serial bus interface circuit operates in the free data format (ALS = 1), the AAS is set to “1” after
The AAS is cleared to “0” by writing data to the SBIDBR or reading data from the SBIDBR.
The AD0 (Bit1 in SBISRB) is set to “1” when all 8-bit received data is “0” immediately after a start condition
The SDA line value stored at the rising edge of the SCL line is set to the LRB (Bit0 in SBISRB). In the
For initialization of device, set the ACK in SBICRA to “1” and the BC to “000”. Specify the data length to 8
Next, set the slave address to the SA in I2CAR and clear the ALS to “0” to set an addressing format.
