Functional Description
SMBus timeouts interrupt is driven by SLTF and masked with the IICIE bit. The SLTF
bit must be cleared by software by writing 1 to it in the interrupt routine. You can
determine the interrupt type by reading the Status Register.
10.4.6.1 Byte Transfer Interrupt
The transfer complete flag (TCF) bit is set at the falling edge of the ninth clock to
indicate the completion of a byte and acknowledgement transfer. When FACK is enabled,
TCF is then set at the falling edge of 8th clock to indicate the completion of byte.
10.4.6.2 Address Detect Interrupt
When the calling address matches the programmed slave address (I2C Address Register)
or when the GCAEN bit is set and a general call is received, the IAAS bit in the Status
Register is set. The CPU is interrupted, provided the IICIE bit is set. The CPU must
check the SRW bit and set its Tx mode accordingly.
10.4.6.3 Exit from Low-Power/Stop Modes
The slave receive input detect circuit and address matching feature are still active on low
power modes (wait and stop). An asynchronous input matching slave address or general
call address brings the CPU out of low power/stop mode if the interrupt is not masked.
Therefore, TCF and IAAS both can trigger this interrupt.

Wakeup from stop interrupt
Complete 1-byte transfer
In master receive mode, the FACK bit must be set to zero
before the last byte transfer.
