For I
For 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.
For I
A wait request can be generated by driving the SCL pin low after data transfer, excluding
acknowledgement.
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
