The EMC1402 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 EMC1402 responds to hard-wired SMBus slave address as shown in
Note: Other addresses are available. Contact SMSC for more information.
The EMC1402 supports 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
SMBus Address
SMBus Timeout
from the device was not prematurely stopped due to a bus contention event).
Register being cleared, the ALERT pin will be reasserted.
