format.
After all data other than the acknowledge bit has been transferred, the system can be placed in
the wait state by setting SCL low. The wait state can be cancelled by clearing the interrupt flag
to 0.
After all data other than the acknowledge bit has been transferred, a request to enter the wait
state can be issued by setting SCL low. The request to enter the wait state is cleared when the
next transfer becomes possible.
Data transfer end (including when a transition to transmit mode is made in the I
when data in ICDR 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 of the I
