The I
interface functions. However, the configuration of the registers that control the I
partly from the Philips register configuration.
Figure 16.1 shows a block diagram of the I
I/O pin connections to external circuits.
16.1
• Selection of I
• Continuous transmission/reception
• Module standby mode can be set
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 function
• Six interrupt sources
• Direct bus drive

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
The data transfer controller (DTC) can be activated by a transmit-data-empty request or
receive-data-full request to transfer data.
Two pins, SCL and SDA pins, function as NMOS open-drain outputs when the bus drive
function is selected.
