16.1
• Continuous transmission/reception
• 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
• Six interrupt sources
• Direct bus drive

functions.
For example: HD6432375WFQ
Since the shift register, transmit data register, and receive data register are independent from
each other, the continuous transmission/reception can be performed.
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.
Transmit-data-empty (including slave-address match), transmit-end, receive-data-full
(including slave-address match), arbitration lost, NACK detection, and stop condition
detection
Two pins, SCL and SDA pins function as NMOS open-drain outputs.
