Selection of I
Continuous transmission/reception
Since the shift register, transmit data register, and receive data register are independent from
each other, the continuous transmission/reception can be performed.
Start and stop conditions generated automatically in master mode
Selection of acknowledge output levels when receiving
Automatic loading of acknowledge bit when transmitting
Bit synchronization/wait function
In master mode, the state of SCL is monitored per bit, and the timing is synchronized
automatically.
If transmission/reception is not yet possible, set the SCL to low until preparations are
completed.
Six interrupt sources
Transmit data empty (including slave-address match), transmit end, receive data full (including
slave-address match), arbitration lost, NACK detection, and stop condition detection
Direct bus drive
Two pins, SCL and SDA pins, function as NMOS open-drain outputs when the bus drive
function is selected.
Four interrupt sources
Transmit-data-empty, transmit-end, receive-data-full, and overrun error
