The EMC1403 and EMC1404 will respond to the ARA in the following way:
1. Send Slave Address and verify that full slave address was sent (i.e. the SMBus communication
2. Set the MASK bit to clear the ALERT pin.
The EMC1403 and EMC1404 respond to hard-wired SMBus slave address as shown in
Note: Other addresses are available. Contact SMSC for more information.
The EMC1403 and EMC1404 support SMBus Timeout. If the clock line is held low for longer than
30ms, the device will reset its SMBus protocol. This function can be enabled by setting the TIMEOUT
bit in the Consecutive Alert Register (see
