C bus format: addressing format with acknowledge bit, for master/slave operation
Clocked synchronous serial format: non-addressing format without acknowledge bit, for
master operation only
• Conforms to Philips I
• Two ways of setting slave address (I
• Start and stop conditions generated automatically in master mode (I
• Selection of acknowledge output levels when receiving (I
• Automatic loading of acknowledge bit when transmitting (I
• Wait function in master mode (I
A wait can be inserted by driving the SCL pin low after data transfer, excluding
acknowledgement.
The wait can be cleared by clearing the interrupt flag.
• Wait function (I
2
C bus format)
A wait request can be generated by driving the SCL pin low after data transfer.
The wait request is cleared when the next transfer becomes possible.
• Interrupt sources
Data transfer end (including when a transition to transmit mode with I
when ICDR data is transferred, or during a wait state)
Address match: when any slave address matches or the general call address is received in
slave receive mode with I
arbitration)
Arbitration loss
Start condition detection (in master mode)
Stop condition detection (in slave mode)
• Selection of 32 internal clocks (in master mode)
• Direct bus drive
