The slave device’s INTIICn signal and wait period occur at the falling edge of the ninth clock only when
there is a match with the address set to the SVAn register.
At this point, ACK is generated regardless of the value set to the IICCn.ACKEn bit. For a slave device
that has received an extension code, the INTIICn signal occurs at the falling edge of the eighth clock.
When the address does not match after restart, the INTIICn signal is generated at the falling edge of the
ninth clock, but no wait occurs.
If the received address does not match the contents of the SVAn register and an extension code is not
received, neither the INTIICn signal nor a wait occurs.
and wait control are both synchronized with the falling edge of these clock signals.
