The I
interface functions. However, the configuration of the registers that control the I
partly from the Philips register configuration.
17.1
• Selection of I
• Continuous transmission/reception
I
• 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
• The direct memory access controller (DMAC) can be activated by a transmit-data-empty
• Direct bus drive
Clocked synchronous serial format:
• Four interrupt sources
• The direct memory access controller (DMAC) can be activated by a transmit-data-empty

C bus format:
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
request or receive-data-full request to transfer data.
Two pins, SCL0 to SCL2 and SDA0 to SDA2, function as NMOS open-drain outputs when the
bus drive function is selected.
Transmit-data-empty, transmit-end, receive-data-full, and overrun error
request or receive-data-full request to transfer data.
