The EMC2102 will respond to the ARA command if the ALERT# pin has been asserted but will not
immediately release the ALERT# pin. The ALERT# pin is released under the following conditions.
1. The Interrupt Status Registers are read and the error condition has been removed.
2. The specific error condition is masked from asserting the ALERT# pin.
The EMC2102-1 is addressed on the SMBus as 011_1101b.
Attempting to communicate with the EMC2102 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 EMC2102 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.
