Received by SMBus Slave
First byte transfer the device is the master transmitter and interrupts after the
ACK
The device then becomes the receiver and generates the interrupt based on
the hardware acknowledgement bit (EHACK)
Slave Address
EHACK = 1 then interrupts occur after the ACK/NAK
EHACK = 0 then interrupts occur before the ACK/NAK period and firmware must
write the desired value to the ACK bit
