... Selection". 4.8 SMBus Timeout The EMC1073 and EMC1074 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 SMSC EMC1073 / EMC1074 4 ...
Page 16
... The EMC1073 and EMC1074 have two levels of monitoring. The first provides a maskable ALERT signal to the host when the measured temperatures exceeds user programmable limits. This allows the EMC1073 or EMC1074 to be used as an independent thermal watchdog to warn the host of temperature hot spots without direct control by the host. The second level of monitoring provides a non maskable interrupt on the THERM pin if the measured temperatures meet or exceed a second programmable limit ...

... Diode Faults The EMC1073 and EMC1074 detect an open on the DP and DN pins, and a short across the DP and DN pins. For each temperature measurement made, the device checks for a diode fault on the external diode channel(s). When a diode fault is detected, the ALERT pin asserts (unless masked, see 5.6, " ...
