The EMC2103 will respond to the ARA in the following way if the ALERT pin is asserted.
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 EMC2103 SMBus Address is fixed at 0101_110xb.
Other addresses are available. Contact SMSC for details.
Attempting to communicate with the EMC2103 SMBus interface with an invalid slave address or invalid
protocol will result in no response from the device and will not affect its register contents.
The EMC2103 includes an SMBus time-out feature. Following a 30ms period of inactivity on the
SMBus, the device will time-out and reset the SMBus interface.
